Patristic Wisdom: Looking to the Third Sunday of Easter

Then He said to them, “These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” And He opened their understanding, that they might comprehend the Scriptures. Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. And you are witnesses of these things. Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high.” (Lu 24:44-49)

Then He opened their mind to understand the Scriptures. When He had quieted their reasonings by what He said, by the touch of their hands, and by partaking of food, He then opened their mind to understand, that “so it was necessary for Him to suffer,” even upon the wood of the cross. The Lord therefore recalls the minds of the disciples to what Me had before said: for He had forewarned them of His sufferings upon the cross, according to what the prophets had long before spoken: and He opens also the eyes of their heart, so as for them to understand the ancient prophecies. The Savior promises the disciples the descent of the Holy Spirit, which God had announced of old by Joel, and power from above, that they might be strong and invincible, and without all fear preach to men everywhere the divine mystery. He says to them now that they had received the Spirit after the resurrection, “Receive the Holy Spirit,” and adds, “But tarry at Jerusalem, and wait for the promise of the Father, which you have heard of Me. For John indeed baptized with water, but you must be baptized with the Holy Spirit;” in water no longer, for that they had received, but with the Holy Spirit: He does not add water to water, but completes that which was deficient by adding what was lacking to it. Having blessed them, and gone a little in advance, He was carried up to heaven, that He might share the Father's throne even with the flesh that was united to Him. And this new pathway the Word made for us when He appeared in human form: and hereafter in due time He will come again in the glory of His Father with the angels, and will take us up to be with Him. Let us glorify therefore Him Who being God the Word became man for our sakes: Who suffered willingly in the flesh, and arose from the dead, and abolished corruption: Who was taken up, and hereafter must come with great glory to judge the living and the dead, and to give to every one according to his deeds: by Whom and with Whom to God the Father be glory and power with the Spirit for ever and ever. Amen.
