TRINITY, n. […] The Trinity is one of the most sublime mysteries of our holy religion. In rejecting it because it is incomprehensible, Unitarians betray their inadequate sense of theological fundamentals. In religion we believe only what we do not understand, except in the instance of an intelligible doctrine that contradicts an incomprehensible one. In that case we believe the former as a part of the latter.

Ambrose Bierce (1842-1914?) American writer and journalist
