Bonaventure's View of the Triune God

"If then God is perfect spirit, He has memory, intelligence, and will; and He has both the begotten Word and spirated Love. These are necessarily distinguished, since one is produced from the other--distinguished, not essentially or accidentally, but personally. When therefore the mind considers itself, it rises through itself as through a mirror to the contemplation of the Blessed Trinity--Father, Word, and Love--three persons coeternal, coequal, and consubstantial; so that each one is in each of the others, though one is not the other, but all three are one God" (Journey of the Mind to God 3.5).
