TRINITY

in theology, the term used for the highest mystery of the Christian faith, the doctrine that the Divine Being consists of three persons united fn one God. In the O.T. this doctrine cannot be said to hold a prominent place, for the Jews had to learn the unity of God as opposed to polytheism. Not even in the N.T. is the doctrine of the Ble ed T. found in its fully-developed form. This development was the work of the early centuries, and its expre ion owes most of all to Greek thought. The Chris to logical problem was first discu ed, and the original Nicene Creed enced at the words ‘And I believe in the Holy Ghost.’ The latter paxt was added afterwards, and now the expre ion of the mystery was almost complete. The fullest expre ion, however, is found in the Quicunque Vult, the so-called Creed of St. A than as i us.
