The Orthodox Church as always regarded Theology, (or "Theologia" in Greek) as the direct experience of God through which the truths pertaining to God are revealed by the Holy Spirit. As per Evagrios of Ponticus in the fourth century, "If you are truly a theologian, you truly pray. If you truly pray, you are truly a theologian." In the Orthodox Church, theology, spirituality, worship, prayer, are of a piece. The articles presented here as examples of the breadth and diversity of theological topics, writings and authors.
