Augustine of Hippo

In this human form the good will see him in whom they have believed; the wicked, him whom they have despised. But the wicked will not see him in the form of God in which he is equal to the Father, for as the prophet says, "The wicked shall be taken off that he may not see the glory of the Lord," and, on the other hand, "Blessed are the clean of heart, for they shall see God."
