In his St. Gregory Palamas and the Tradition of the Fathers (also here and here and here as a pdf file), Fr. Georges Florovsky states:
Apart from life in Christ theology carries no conviction and, if separated from the life of faith, theology may degenerate into empty dialectics, a vain polylogia, without any spiritual consequence. Patristic theology was existentially rooted in the decisive commitment of faith. It was not a self-explanatory “discipline” which could be presented argumentatively, that is aristotelikôs, without any prior spiritual engagement. . . . “Theology” is not an end in itself. It is always but a way. Theology, and even the “dogmas,” present no more than an “intellectual contour” of the revealed truth, and a “noetic” testimony to it. Only in the act of faith is this “contour” filled with content. Christological formulas are fully meaningful only for those who have encountered the Living Christ, and have received and acknowledged Him as God and Saviour, and are dwelling by faith in Him, in His body, the Church. In this sense, theology is never a self-explanatory discipline. It is constantly appealing to the vision of faith.
It is this "vision of faith," this phronema, or mind of the Church, that is exemplified in St. Gregory Palamas--whom we will celebrate and whose prayers we will invoke this coming Sunday. Fr. Georges continues his article discussing St. Gregory and theosis--cdh.
What is the basic character of Christian existence? The ultimate aim and purpose of human life was defined in the Patristic tradition as theosis [divinization]. The term is rather offensive for the modern ear. It cannot be adequately rendered in any modern language, nor even in Latin. Even in Greek it is rather heavy and pretentious. Indeed, it is a daring word. The meaning of the word is, however, simple and lucid. It was one of the crucial terms in the Patristic vocabulary. It would suffice to quote at this point but St. Athanasius. Gegonen gar anthropos, hin hemas en heauto theopoiese. [He became man in order to divinize us in Himself (Ad Adelphium 4)]. Autos gar enenthropesen, hina hemeis theopoiethomen. [He became man in order that we might be divinized (De Incarnatione 54)]. St. Athanasius actually resumes here the favourite idea of St. Irenaeus: qui propter immensam dilectionem suam factus est quod sumus nos, uti nos perficeret esse quod est ipse. [Who, through his immense love became what we are, that He might bring us to be even what He is Himself (Adv. Haeres. V, Praefatio)]. It was the common conviction of the Greek Fathers. One can quote at length St. Gregory of Nazianzus. St. Gregory of Nyssa, St. Cyril of Alexandria, St. Maximus, and indeed St. Symeon the New Theologian. Man ever remains what he is, that is, creature. But he is promised and granted, in Christ Jesus, the Word become man, an intimate sharing in what is Divine: Life Everlasting and incorruptible. The main characteristic of theosis is, according
