Phronema is a transliteration of the Greek word φρόνημα, which has the meanings of "mind", "spirit", "thought", "purpose", "will", and can have either a positive meaning ("high spirit", "resolution", "pride") or a bad sense ("presumption", "arrogance").
In the New Testament, the word is used four times in the Saint Paul's Letter to the Romans: twice with "τῆς σαρκός" (of the flesh) and twice with "τοῦ πνεύματος" (of the spirit): "for the mind of the flesh [is] death, and the mind of the Spirit – life and peace; because the mind of the flesh [is] enmity to God ...and He who is searching the hearts hath known what [is] the mind of the Spirit" (Romans 8:6-7,27).
Eastern Orthodox theologyEdit
The term phronema is used in Eastern Orthodox theology to one particular mindset or outlook – the Orthodox mind. The attaining of phronema in this sense is a matter of practicing the correct faith (orthodoxia) in the correct manner (orthopraxis). Attaining phronema is regarded as the first step toward theosis, the state of glorification. 
Phronema is also the name of the official annual review of St Andrew's Greek Orthodox Theological College, Sydney, Australia. It presents articles and book reviews from Orthodox and non-Orthodox on topics with central reference to theology, Church history and Orthodoxy.
Use by John Henry NewmanEdit
The term was used in by John Henry Newman in an article published in 1859 under the title "On Consulting the Faithful in Matters of Doctrine". He said that the consensus of the faithful is to be regarded as "a sort of instinct, or phronēma, deep in the bosom of the mystical body of Christ".

- The appeal to Tradition was actually an appeal to the mind of the Church, her phronema. It was a method to discover and ascertain the faith as it had been always held, from the very beginning: semper creditum. The permanence of Christian belief was the most conspicuous sign and token of its truth: no innovations [For further discussion of this topic see my articles: "The Function of Tradition in the Ancient Church," The Greek Orthodox Theological Review, IX (No. 2, 1964), 181-200, and "Scripture and Tradition: An Orthodox point of view," Dialog, II (No. 4, 1963), 288-293.
