. . . the climax of purity is the foundation of theology. He who has perfectly united his feelings to God is mystically led by Him to an understanding of His words. But without this union it is difficult to speak about God. The engrafted Word perfects purity, and slays death by His presence; and after slaying death, the disciple of divine knowledge is enlightened. The Word of the Lord which is from God the Father is pure, and remains so eternally. But he who has not come to know God merely speculates. Purity makes its disciple a theologian, who of himself grasps the dogmas of the Trinity.
