Augustine of Hippo defined the Latin equivalent, theologia, as "reasoning or discussion concerning the Deity"; Richard Hooker defined "theology" in English as "the science of things divine". The term can, however, be used for a variety of different disciplines or fields of study. Theologians use various forms of analysis and argument (philosophical, ethnographic, historical, spiritual and others) to help understand, explain, test, critique, defend or promote any of myriad religious topics. Specifically, the study of theology may help a theologian more deeply understand their own religious tradition,  another religious tradition,  or it may enable them to explore the nature of divinity without reference to any specific tradition. Theology may be used to propagate,  reform,  or justify a religious tradition or it may be used to compare,  challenge (e.g. biblical criticism), or oppose (e.g. irreligion) a religious tradition or world-view. Theology might also help a theologian to address some present situation or need through a religious tradition,  or to explore possible ways of interpreting the world. 
Theology translates into English from the Greek theologia (θεολογία) which derived from Τheos (Θεός), meaning "God," and -logia (-λογία), meaning "utterances, sayings, or oracles" (a word related to logos [λόγος], meaning "word, discourse, account, or reasoning") which had passed into Latin as theologia and into French as théologie. The English equivalent "theology" (Theologie, Teologye) had evolved by 1362. The sense the word has in English depends in large part on the sense the Latin and Greek equivalents had acquired in patristic and medieval Christian usage, although the English term has now spread beyond Christian contexts.
Greek theologia (θεολογία) was used with the meaning "discourse on god" in the fourth century BC by Plato in The Republic, Book ii, Ch. 18. Aristotle divided theoretical philosophy into mathematike, physike and theologike, with the latter corresponding roughly to metaphysics, which, for Aristotle, included discourse on the nature of the divine.
Drawing on Greek Stoic sources, the Latin writer Varro distinguished three forms of such discourse: mythical (concerning the myths of the Greek gods), rational (philosophical analysis of the gods and of cosmology) and civil (concerning the rites and duties of public religious observance).
Theologos, closely related to theologia, appears once in some biblical manuscripts, in the heading to the Book of Revelation: apokalypsis ioannoy toy theologoy, "the revelation of John the theologos." There, however, the word refers not to John the "theologian" in the modern English sense of the word but—using a slightly different sense of the root logos, meaning not "rational discourse" but "word" or "message"—one who speaks the words of God, logoi toy theoy.
Some Latin Christian authors, such as Tertullian and Augustine, followed Varro's threefold usage, though Augustine also used the term more simply to mean 'reasoning or discussion concerning the deity'
The Latin author Boethius, writing in the early 6th century, used theologia to denote a subdivision of philosophy as a subject of academic study, dealing with the motionless, incorporeal reality (as opposed to physica, which deals with corporeal, moving realities). Boethius' definition influenced medieval Latin usage.
In scholastic Latin sources, the term came to denote the rational study of the doctrines of the Christian religion, or (more precisely) the academic discipline which investigated the coherence and implications of the language and claims of the Bible and of the theological tradition (the latter often as represented in Peter Lombard's Sentences, a book of extracts from the Church Fathers).
In the Renaissance, especially with Florentine Platonist apologists of Dante's poetics, the distinction between "poetic theology" (theologia poetica) and "revealed" or Biblical theology serves as steppingstone for a revival of philosophy as independent of theological authority.
It is in this last sense, theology as an academic discipline involving rational study of Christian teaching, that the term passed into English in the fourteenth century, although it could also be used in the narrower sense found in Boethius and the Greek patristic authors, to mean rational study of the essential nature of God – a discourse now sometimes called Theology Proper.
From the 17th century onwards, it also became possible to use the term theology to refer to study of religious ideas and teachings that are not specifically Christian (e.g., in the term natural theology which denoted theology based on reasoning from natural facts independent of specifically Christian revelation,) or that are specific to another religion (see below).
"Theology" can also now be used in a derived sense to mean "a system of theoretical principles; an (impractical or rigid) ideology."
The term Theology has been deemed by some as only appropriate to the study of religions that worship a supposed deity (a theos), i.e. more widely than the Judeo-Christian tradition; and presuppose a belief in the ability to speak and reason about this deity (in logia). They suggest the term is less appropriate in religious contexts that are organized differently (religions without a single deity, or that deny that such subjects can be studied logically). ("Hierology" has been proposed as an alternative, more generic term.)
Islamic theological discussion that parallels Christian theological discussion is named "Kalam"; the Islamic analogue of Christian theological discussion would more properly be the investigation and elaboration of Sharia or Fiqh. "Kalam ... does not hold the leading place in Muslim thought that theology does in Christianity. To find an equivalent for 'theology' in the Christian sense it is necessary to have recourse to several disciplines, and to the usul al-fiqh as much as to kalam." (L. Gardet)
Some academic inquiries within Buddhism, dedicated to the investigation of a Buddhist understanding of the world, prefer the designation Buddhist philosophy to the term Buddhist theology, since Buddhism lacks the same conception of a theos. Jose Ignacio Cabezon, who argues that the use of "theology" is appropriate, can only do so, he says, because "I take theology not to be restricted to discourse on God ... I take 'theology' not to be restricted to its etymological meaning. In that latter sense, Buddhism is of course atheological, rejecting as it does the notion of God."
Within Hindu philosophy, there is a solid and ancient tradition of philosophical speculation on the nature of the universe, of God (termed "Brahman", Paramatma and Bhagavan in some schools of Hindu thought) and of the Atman (soul). The Sanskrit word for the various schools of Hindu philosophy is Darshana (meaning "view" or "viewpoint"). Vaishnava theology has been a subject of study for many devotees, philosophers and scholars in India for centuries, and in recent decades also has been taken on by a number of academic institutions in Europe, such as the Oxford Centre for Hindu Studies and Bhaktivedanta College.

In Judaism, the historical absence of political authority has meant that most theological reflection has happened within the context of the Jewish community and synagogue, rather than within specialized academic institutions. Nevertheless, Jewish theology historically has been very active and highly significant for Christian and Islamic theology. It is sometimes claimed, however, that the Jewish analogue of Christian theological discussion would more properly be Rabbinical discussion of Jewish law and Jewish Biblical commentaries.
Theology as an academic disciplineEdit
The history of the study of theology in institutions of higher education is as old as the history of such institutions themselves. For instance, Taxila was an early centre of Vedic learning, possible from the 6th century BC or earlier; the Platonic Academy founded in Athens in the 4th century BC seems to have included theological themes in its subject matter; the Chinese Taixue delivered Confucian teaching from the 2nd century BC; the School of Nisibis was a centre of Christian learning from the 4th century AD; Nalanda in India was a site of Buddhist higher learning from at least the 5th or 6th century AD; and the Moroccan University of Al-Karaouine was a centre of Islamic learning from the 10th century, as was Al-Azhar University in Cairo.
The earliest universities were developed under the aegis of the Latin Church by papal bull as studia generalia and perhaps from cathedral schools. It is possible, however, that the development of cathedral schools into universities was quite rare, with the University of Paris being an exception. Later they were also founded by Kings (University of Naples Federico II, Charles University in Prague, Jagiellonian University in Kraków) or municipal administrations (University of Cologne, University of Erfurt). In the early medieval period, most new universities were founded from pre-existing schools, usually when these schools were deemed to have become primarily sites of higher education. Many historians state that universities and cathedral schools were a continuation of the interest in learning promoted by monasteries. Christian theological learning was therefore a component in these institutions, as was the study of Church or Canon law: universities played an important role in training people for ecclesiastical offices, in helping the church pursue the clarification and defence of its teaching, and in supporting the legal rights of the church over against secular rulers. At such universities, theological study was initially closely tied to the life of faith and of the church: it fed, and was fed by, practices of preaching, prayer and celebration of the Mass.
During the High Middle Ages, theology was therefore the ultimate subject at universities, being named "The Queen of the Sciences" and serving as the capstone to the Trivium and Quadrivium that young men were expected to study. This meant that the other subjects (including Philosophy) existed primarily to help with theological thought.
Christian theology’s preeminent place in the university began to be challenged during the European Enlightenment, especially in Germany. Other subjects gained in independence and prestige, and questions were raised about the place in institutions that were increasingly understood to be devoted to independent reason of a discipline that seemed to involve commitment to the authority of particular religious traditions.
Since the early nineteenth century, various different approaches have emerged in the West to theology as an academic discipline. Much of the debate concerning theology's place in the university or within a general higher education curriculum centres on whether theology's methods are appropriately theoretical and (broadly speaking) scientific or, on the other hand, whether theology requires a pre-commitment of faith by its practitioners, and whether such a commitment conflicts with academic freedom.
Theology and ministerial trainingEdit
In some contexts, theology has been held to belong in institutions of higher education primarily as a form of professional training for Christian ministry. This was the basis on which Friedrich Schleiermacher, a liberal theologian, argued for the inclusion of theology in the new University of Berlin in 1810.
For instance, in Germany, theological faculties at state universities are typically tied to particular denominations, Protestant or Roman Catholic, and those faculties will offer denominationally-bound (konfessionsgebunden) degrees, and have denominationally bound public posts amongst their faculty; as well as contributing ‘to the development and growth of Christian knowledge’ they ‘provide the academic training for the future clergy and teachers of religious instruction at German schools.’
In the United States, several prominent colleges and universities were started in order to train Christian ministers. Harvard, Georgetown, Boston University, Yale, and Princeton all had the theological training of clergy as a primary purpose at their foundation.
Seminaries and bible colleges have continued this alliance between the academic study of theology and training for Christian ministry. There are, for instance, numerous prominent US examples, including Catholic Theological Union in Chicago, The Graduate Theological Union in Berkeley, Criswell College in Dallas, The Southern Baptist Theological Seminary in Louisville, Trinity Evangelical Divinity School in Deerfield, Illinois, Dallas Theological Seminary, North Texas Collegiate Institute in Farmers Branch, Texas  and The Assemblies of God Theological Seminary in Springfield, Missouri.
Theology as an academic discipline in its own rightEdit
In some contexts, scholars pursue theology as an academic discipline without formal affiliation to any particular church (though members of staff may well have affiliations to churches), and without focussing on ministerial training. This applies, for instance, to many university departments in the United Kingdom, including the Faculties of Divinity at the University of Cambridge and University of Oxford, the Department of Theology and Religion at the University of Exeter, and the Department of Theology and Religious Studies at the University of Leeds. Traditional academic prizes, such as the University of Aberdeen's Lumsden and Sachs Fellowship, tend to acknowledge performance in theology (or divinity as it is known at Aberdeen) and in religious studies.
Theology and religious studiesEdit
In some contemporary contexts, a distinction is made between theology, which is seen as involving some level of commitment to the claims of the religious tradition being studied, and religious studies, which by contrast is normally seen as requiring that the question of the truth or falsehood of the religious traditions studied be kept outside its field. Religious studies involves the study of historical or contemporary practices or of those traditions' ideas using intellectual tools and frameworks that are not themselves specifically tied to any religious tradition and that are normally understood to be neutral or secular. In contexts where 'religious studies' in this sense is the focus, the primary forms of study are likely to include:
- Anthropology of religion
- Comparative religion
- History of religions
- Philosophy of religion
- Psychology of religion
- Sociology of religion
Sometimes, theology and religious studies are seen as being in tension, and at other times, they are held to coexist without serious tension. Occasionally it is denied that there is as clear a boundary between them.
Criticism by philosophersEdit
Whether or not reasoned discussion about the divine is possible has long been a point of contention.
Protagoras, as early as the fifth century BC, who is reputed to have been exiled from Athens because of his agnosticism about the existence of the gods, said that "Concerning the gods I cannot know either that they exist or that they do not exist, or what form they might have, for there is much to prevent one's knowing: the obscurity of the subject and the shortness of man's life."
Lord Bolingbroke, an English politician and political philosopher wrote in his political works his views on theology, "Theology is in fault not religion. Theology is a science that may justly be compared to the Box of Pandora. Many good things lie uppermost in it; but many evil lie under them, and scatter plagues and desolation throughout the world."
Thomas Paine the American revolutionary, wrote in his two part work The Age of Reason, "The study of theology, as it stands in Christian churches, is the study of nothing; it is founded on nothing; it rests on no principles; it proceeds by no authorities; it has no data; it can demonstrate nothing; and it admits of no conclusion. Not anything can be studied as a science, without our being in possession of the principles upon which it is founded; and as this is the case with Christian theology, it is therefore the study of nothing."
Ludwig Feuerbach, the atheist philosopher sought to dissolve theology in his work Principles of the Philosophy of the Future: "The task of the modern era was the realization and humanization of God – the transformation and dissolution of theology into anthropology." This mirrored his earlier work The Essence of Christianity (pub. 1841), for which he was banned from teaching in Germany, in which he had said that theology was a "web of contradictions and delusions".
A.J. Ayer the former logical-positivist, sought to show in his essay "Critique of Ethics and Theology" that all statements about the divine are nonsensical and any divine-attribute is unprovable. He wrote: "It is now generally admitted, at any rate by philosophers, that the existence of a being having the attributes which define the god of any non-animistic religion cannot be demonstratively proved... [A]ll utterances about the nature of God are nonsensical."
Walter Kaufmann the philosopher, in his essay "Against Theology", sought to differentiate theology from religion in general. "Theology, of course, is not religion; and a great deal of religion is emphatically anti-theological... An attack on theology, therefore, should not be taken as necessarily involving an attack on religion. Religion can be, and often has been, untheological or even anti-theological." However, Kaufmann found that "Christianity is inescapably a theological religion".
Critics of theology as an academic disciplineEdit
Charles Bradlaugh believed theology prevented human beings achieving liberty. Bradlaugh noted theologians of his time stated that modern scientific research contradicted sacred scriptures therefore the scriptures must be wrong.
Robert G. Ingersoll stated that when theologians had power the majority of people lived in hovels while a privileged few had palaces and cathedrals. In Ingersoll's opinion science rather than theology improved people's lives. Ingersoll maintained further that trained theologians reason no better than a person who assumes the devil must exist because pictures resemble the devil so exactly.
