First Reading — Ephesians 2:19-22
Clement of Alexandria
On 2:20
Understand now for me the mystery of the truth, granting pardon if I shrink from advancing further in the treatment of it, by announcing this alone: "All things were made by Him, and without Him was not even one thing." Certainly He is called "the chief corner stone; in whom the whole building, fitly joined together, groweth into an holy temple of God," according to the divine apostle.
Responsorial Psalm — Psalm 117:1bc, 2
Augustine of Hippo
On 116:1
"O praise the Lord, all you heathen: praise Him, all you nations." These are the courts of the Lord's house, this all His people, this the true Jerusalem. Let those rather listen who have refused to be the children of this city, since they have cut themselves off from the communion of all nations.
On 116:2
"For His merciful kindness is ever more and more towards us: and the truth of the Lord endures for ever." These are those two things, loving-kindness and truth, which in the CXVth Psalm I admonished you should be committed to memory. But "the merciful kindness of the Lord is ever more and more towards us," since the furious tongues of hostile nations have yielded to His Name, through which we have been freed: "and the truth of the Lord endures for ever," whether in those things which He promised to the righteous, or in those which He has threatened to the ungodly.
Gospel — John 20:24-29
John Chrysostom
On 20:24
(Hom. lxxxvi. 4) A priest though he may have ordered well his own life, yet, if he have not exercised proper vigilance over others, is sent to hell with the evil doers. Wherefore, knowing the greatness of their danger, pay them all respect, even though they be not men of notable goodness. For they who are in rule, should not be judged by those who are under them. And their incorrectness of life will not at all invalidate what they do by commission from God. For not only cannot a priest, but not even angel or archangel, do any thing of themselves; the Father, Son, and Holy Ghost do all. The priest only furnishes the tongue, and the hand. For it were not just that the salvation of those who come to the Sacraments in faith, should be endangered by another’s wickedness. (Hom. lxxxvii. 1). At the assembly of the disciples all were present but Thomas, who probably had not returned from the dispersion: But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.
On 20:25
(Hom. lxxxvii. 1) As to believe directly, (ἁπλῶς) and any how, is the mark of too easy a mind, so is too much enquiring of a gross one: and this is Thomas’s fault. For when the Apostle said, We have seen the Lord, he did not believe, not because he discredited them, but from an idea of the impossibility of the thing itself: The other disciples therefore said unto him, We have seen the Lord. But he said unto them, Except I shall see in His hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into His side, I will not believe. Being the grossest of all, he required the evidence of the grossest sense, viz. the touch, and would not even believe his eyes: for he does not say only, Except I shall see, but adds, and put my finger into the print of the nails, and thrust my hand into His side.
On 20:26
(Hom. lxxxvii) Consider the mercy of the Lord, how for the sake of one soul, He exhibits His wounds. And yet the disciples deserved credit, and He had Himself foretold the event. Notwithstanding, because one person, Thomas, would examine Him, Christ allowed him. But He did not appear to him immediately, but waited till the eighth day, in order that the admonition being given in the presence of the disciples, might kindle in him greater desire, and strengthen his faith for the future. And after eight days again His disciples were within, and Thomas with them: then came Jesus, the doors being shut, and stood in the midst, and said, Peace be unto you.
On 20:26
(Hom. lxxxvii) John having related less than the other Evangelists, adds, And many other signs truly did Jesus in the presence of His disciples, which are not written in this book. Yet neither did the others relate all, but only what was sufficient for the purpose of convincing men. He probably here refers to the miracles which our Lord did after His resurrection, and therefore says, In the presence of His disciples, and they being the only persons with whom He conversed after His resurrection. Then to let you understand, that the miracles were not done for the sake of the disciples only, He adds, But these are written, that ye might believe that Jesus is the Christ, the Son of God; addressing Himself to mankind generally. And, this belief, he then says, profits ourselves, not Him in Whom we believe. And that believing ye might have life through His name, i. e. through Jesus, which is life.
On 20:27
(Hom. lxxxvii. 1) Jesus then comes Himself, and does not wait till Thomas interrogates Him. But to shew that He heard what Thomas said to the disciples, He uses the same words. And first He rebukes him; Then saith He to Thomas, Reach hither thy finger, and behold My hands; and reach hither thy hand, and thrust it into My side: secondly, He admonishes him; And be not faithless, but believing. Note how that before they receive the Holy Ghost faith wavers, but afterward is firm. We may wonder how an incorruptible body could retain the marks of the nails. But it was done in condescension; in order that they might be sure that it was the very person Who was crucified.
On 20:29
(Hom. lxxxvii) If any one then says, Would that I had lived in those times, and seen Christ doing miracles! let him reflect, Blessed are they that have not seen, and yet have believed.
