Athanasius of Alexandria, on Exod 12:14

“And this day shall be for a memorial to you: and you shall keep it a feast to the Lord in your generations with an everlasting observance.”

“As also the Word of God, when desirous [to establish the paschal feast] said to his disciples, "With desire I have desired to eat this Passover with you." Now that is a wonderful account, for a man might have seen them at that time girded as for a procession or a dance and going out with staves and sandals and unleavened bread. These things, which took place before in shadows, were typical anticipatory symbols. But now the truth has drawn near to us, "the image of the invisible God," our Lord Jesus Christ, the true Light. Instead of a staff, he is our scepter; instead of unleavened bread, he is the bread which came down from heaven; who instead of sandals has furnished us with the preparation of the gospel. It is he who, to speak briefly, by all these means has guided us to his Father. And if enemies afflict us and persecute us, he again, instead of Moses, will encourage us with better words, saying, "Be of good cheer; I have overcome the wicked one." And if after we have passed over the Red Sea, heat should again vex us or some bitterness of the waters befall us, even then again the Lord will appear to us, imparting to us of his sweetness and his life-giving fountain, saying, "If any man thirst, let him come to me and drink."”
