The doctrine of the Trinity is not so...

The doctrine of the Trinity is not so much a point among many as the very essence and compendium of Christianity itself. It not only presents a lofty and sublime subject of contemplation to the intellect, but furnishes repose and peace to the heart and conscience. To explain this mystery is not our province. All true theologians ... have universally accepted it as their highest function simply to 'conserve the mystery'... As this doctrine is believed on the one hand or challenged on the other, Christian life is found to be affected at its roots and over all its extent. Every doctrine is run up to it; every privilege and duty hangs on it... However a man may begin his career of error, the general issue is that the doctrine of the Trinity, proving an unexpected check or insurmountable obstacle in the carrying out of his opinions, has to be modified or pushed aside; and he comes to be against the Trinity because he has found it was against him.
