Augustine of Hippo

Again, in ancient times, in the case of the faithful servant of God, Moses, who was destined to labor on this earth and to rule the chosen people, it would not be surprising that what he asked was granted: that he might see the glory of the Lord, to whom he said, "If I have found favor before you, show me yourself openly." He received an answer adapted to present conditions: that he could not see the face of God, because no man could see him and live. Thus God made clear that the vision belongs to another and better life. In addition to that, the mystery of the future church of Christ was foreshadowed by the words of God.
