The Trinity is a mystery…man cannot comprehend it and make it intelligible. It is intelligible in some of its relations and modes of manifestation, but unintelligible in its essential nature…. The real difficulty lies in the relation in which the persons in the Godhead stand to the divine essence and to one another; and this is a difficulty which the Church cannot remove, but only try to reduce to its proper proportion by a proper definition of terms. It has never tried to explain the mystery of the Trinity but only sought to formulate the doctrine of the Trinity in such a manner that the errors which endangered it were warded off.
