Athanasius of Alexandria : In the face of all this, brothers and sisters, what should we do but give thanks to God, the king of all? Let us start by crying out the words of the psalm, "Blessed is the Lord, who has not let them eat us up." Let us keep the feast in that way that he has established for our salvation—the holy day of Easter—so that we, along with the angels, may celebrate the heavenly feast. Remember that Israel, coming out of affliction to a state of rest, sang a song of praise for the victory as they kept the feast. And in the time of Esther the people kept a feast to the Lord because they had been delivered from a deadly decree. They called a feast, thanking and praising the Lord because he had changed the situation for them. Therefore, let us keep our promises to the Lord, confess our sins, and keep the feast to him—in behavior, moral conduct, and way of life. Let us keep it by praising the Lord, who has disciplined us so lightly but has never failed us nor forsaken us nor stopped speaking to us. — FESTAL LETTERS 8 Athanasius of Alexandria : When the whole nation of Israel was about to perish, blessed Esther defeated the tyrant's anger simply by fasting and praying to God. By faith she changed the ruin of her people into safety. Those days are feast days for Israel; they used to call a feast when an enemy was slain or a conspiracy against the people was broken up and Israel was delivered. That is why Moses established the Feast of the Passover: because Pharaoh was killed and the people were delivered from bondage. So then, especially when tyrants were slain, temporal feasts and holidays were established in Judea. Now, however, the devil, that tyrant against the whole world, is slain. Therefore, our feast does not relate only to time but to eternity. It is a heavenly feast! We do not announce it as a shadow or a picture or a type but as the real thing. — FESTAL LETTERS 4
