In the multiplex theism of certain Christian churches, three entirely distinct deities consistent with only one. Subordinate deities of the polytheistic faith, such as devils and angels, are not dowered with the power of combination, and must urge individually their clames to adoration and propitiation. 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.
The union of three persons (the Father, the Son, and the Holy Ghost) in one Godhead, so that all the three are one God as to substance, but three persons as to individuality.
Any union of three in one; three units treated as one; a triad, as the Hindu trinity, or Trimurti.
