Lex orandi, lex credendi.
The law of prayer, the law of belief.
The way we worship, the way we believe.
Lex orandi, lex credendi. This Latin phrase presents one of the great principles of the ancient Christian Faith - that what we believe and how we pray and worship are intimately connected. The Orthodox Christian Church has held fast to this great truth in every generation. For us, doctrine cannot exist separately from prayer or spirituality; change in the nature or form of worship inevitably leads to a change in what we believe and how we live.
Far from being separate and independent categories, doctrine, spirituality, morality, prayer and worship form a single whole that might best be called The Way. This earliest description of the Christian Faith points to the all-encompassing way of life that the Apostolic Church knew to be "the new life in Christ."
Thus, in the Orthodox Faith, theology is not an academic, philosophical discipline to be learned through reading or study. Such an approach inevitably leads to speculation and conjecture. Rather, a true theologian is one who truly prays - one whose nous (or heart, as it is described in Holy Scripture) has been purified by divine grace - and has been blessed to "see God," an experience identical to that of Peter, James and John on Mount Tabor.
