From the Catecheses by St John Chrysostom

The Israelites witnessed marvels; you also will witness marvels, greater and more splendid than those which accompanied them on their departure from Egypt. You did not see Pharaoh drowned with his armies, but you have seen the devil with his weapons overcome by the waters of baptism. The Israelites passed through the sea; you have passed from death to life. They were delivered from the Egyptians; you have been delivered from the powers of darkness. The Israelites were freed from slavery to a pagan people; you have been freed from the much greater slavery to sin.

In those days Christ was present to the Israelites as he followed them, but he is present to us in a much deeper sense. The Lord was with them because of the favor he showed to Moses; now he is with us, but not simply because of your obedience. After Egypt they dwelt in desert places; after your departure you will dwell in heaven. Their great leader and commander was Moses; we have a new Moses, God himself, as our leader and commander.

In those days Moses raised his hands to heaven and brought down manna, the bread of angels; the new Moses raises his hands to heaven and gives us the food of eternal life. Moses struck the rock and brought forth streams of water; Christ touches his table, strikes the spiritual rock of the new covenant and draws forth the living water of the Spirit. This rock is like a fountain in the midst of Christ’s table, so that on all sides the flocks may draw near to this living spring and refresh themselves in the waters of salvation.

Since this fountain, this source of life, this table surrounds us with untold blessings and fills us with the gifts of the Spirit, let us approach it with sincerity of heart and purity of conscience to receive grace and mercy in our time of need. Grace and mercy be yours from the only-begotten Son, our Lord and Saviour Jesus Christ; through him and with him be glory, honour and power to the Father and the life-giving Spirit, now and always and for ever. Amen.
