Changes

At that time, the idea of Infallibility was thought to be an exclusively Roman Catholic idea, entirely alien to the Orthodox Church. However, Fr Stylianos wrote his thesis on the concept that the Orthodox Church did possess the concept of infallibility, when it acted together in conciliarity (eg the Ecumenical Councils); it is only recently that this work is being properly understood and appreciated.

==Educational Accolades==

In 1965, whilst still completing his postgraduate studies, Fr Stylianos was declared professor of theology at Athens University; soon after, in 1966, he was appointed abbot of the Holy Patriarchal Monastery of Vlatodon, Thessaloniki. In this role, he was a founding member, then vice-president, and later president, of the Patriarchal Institute of Patristic Studies within the monastery. During 1969 to 1975, Abbot Stylianos lectured in Systematic Theology at the University of Thessaloniki.
