God is infinite; faith proposes the infinite to us. God is one and triune; faith proposes Him to us as one and triune. In the same way that God is darkness to our mind, faith enlightens our understanding by blinding it. By this means only does God manifest Himself to the soul in a divine light which exceeds all understanding; whence it results that the greater faith is, the more profound is the union… For under the darkness of faith, the understanding is united to God; under cover of this mysterious darkness, God is found hidden.
Saint John of the Cross
