The CHRISTIANITY PORTAL
Showcased Christianity content
Christianity is a monotheistic religion based on the life and teachings of Jesus Christ. It is the world's largest religion, with over 2.4 billion followers, known as Christians. Christians believe that Jesus is the Son of God and the savior of humanity whose coming as the Messiah (the Christ) was prophesied in the Old Testament.
Christian theology is summarized in various creeds. These professions of faith state that Jesus suffered, died, was buried, descended into hell, and rose from the dead, in order to grant eternal life to those who believe in him and trust in him for the remission of their sins. The creeds further maintain that Jesus bodily ascended into heaven, where he reigns with God the Father in the unity of the Holy Spirit, and that he will return to judge the living and the dead and grant eternal life to his followers. His incarnation, earthly ministry, crucifixion, and resurrection are often referred to as "the gospel", meaning "good news". The term gospel also refers to written accounts of Jesus's life and teaching, four of which—Matthew, Mark, Luke, and John—are considered canonical and included in the Christian Bible.
Christianity began as a Second Temple Judaic sect in the mid-1st century. Throughout its history, the religion has weathered schisms and theological disputes that have resulted in many distinct churches and denominations. Worldwide, the three largest branches of Christianity are the Catholic Church, the Eastern Orthodox Church, and the various denominations of Protestantism. The Catholic and Eastern Orthodox churches broke communion with each other in the East-West Schism of 1054; Protestantism came into existence in the Reformation of the 16th century, splitting from the Catholic Church.
The Crusades were a series of religious expeditionary wars blessed by the Pope and the Roman Catholic Church, with the stated goal of restoring Christian access to the holy places in and near Jerusalem. The Crusades were originally launched in response to a call from the leaders of the Byzantine Empire for help to fight the expansion into Anatolia of Muslim Seljuk Turks who had cut off access to Jerusalem. The crusaders comprised military units of Roman Catholics from all over western Europe, and were not under unified command. The main series of Crusades, primarily against Muslims, occurred between 1095 and 1291. Historians have given many of the earlier crusades' timeframes. After some early successes, the later crusades failed and the crusaders were defeated and forced to return home.
Huldrych Zwingli (1 January 1484 – 11 October 1531) was a leader of the Reformation in Switzerland. Born during a time of emerging Swiss patriotism and increasing criticism of the Swiss mercenary system, he attended the University of Vienna and the University of Basel, a scholarly centre of humanism. He continued his studies while he served as a pastor in Glarus and later in Einsiedeln where he was influenced by the writings of Erasmus.
In 1518, Zwingli became the pastor of the Grossmünster in Zurich where he began to preach ideas on reforming the Catholic Church. In his first public controversy in 1522, he attacked the custom of fasting during Lent. In his publications, he noted corruption in the ecclesiastical hierarchy, promoted clerical marriage, and attacked the use of images in places of worship. In 1525, Zwingli introduced a new communion liturgy to replace the mass. Zwingli also clashed with the Anabaptists, which resulted in their persecution.
The Reformation spread to other parts of the Swiss Confederation, but several cantons resisted, preferring to remain Catholic. Zwingli formed an alliance of Reformed cantons which divided the Confederation along religious lines. In 1529, a war between the two sides was averted at the last moment. Meanwhile, Zwingli’s ideas came to the attention of Martin Luther and other reformers. They met at the Marburg Colloquy and although they agreed on many points of doctrine, they could not reach an accord on the doctrine of the presence of Christ in the eucharist. In 1531 Zwingli’s alliance applied an unsuccessful food blockade on the Catholic cantons. The cantons responded with an attack at a moment when Zurich was badly prepared. Zwingli was killed in battle at the age of 47. His legacy lives on in the confessions, liturgy, and church orders of the Reformed churches of today.
A Christian martyr is a person who is killed for following Christianity, through stoning, crucifixion, burning at the stake or other forms of torture and capital punishment. The word "martyr" comes from the Greek word μάρτυς, mártys, which means "witness." At first, the term applied to Apostles. Once Christians started to undergo persecution, the term came to be applied to those who suffered hardships for their faith. Finally, it was restricted to those who had been killed for their faith. The early Christian period before Constantine I was the "Age of martyrs". A martyr's death was considered a "baptism in blood," cleansing one of sin, similar to the effect of baptism in water. Early Christians venerated martyrs as powerful intercessors, and their utterances were treasured as inspired by the Holy Spirit.
