First Reading — Acts 1:1-11
Justin Martyr
On 1:9
Why did He rise in the flesh in which He suffered, unless to show the resurrection of the flesh? And wishing to confirm this, when His disciples did not know whether to believe He had truly risen in the body, and were looking upon Him and doubting, He said to them, "Ye have not yet faith, see that it is I;" and He let them handle Him, and showed them the prints of the nails in His hands. And when they were by every kind of proof persuaded that it was Himself, and in the body, they asked Him to eat with them, that they might thus still more accurately ascertain that He had in verity risen bodily; and He did eat honey-comb and fish. And when He had thus shown them that there is truly a resurrection of the flesh, wishing to show them this also, that it is not impossible for flesh to ascend into heaven (as He had said that our dwelling-place is in heaven), "He was taken up into heaven while they beheld," as He was in the flesh.
Responsorial Psalm — Psalm 47:2-3, 6-7, 8-9
John Chrysostom
On 46:2
With hands that were previously defiled, accursed, daily stained with blood in the impure sacrifices in which you took the lives of your children, performed shameful rites and went beyond the limits of nature itself, with these hands now clap. "Shout to God in a voice of happiness." With that tongue by which you tasted accursed things, by which you uttered blasphemous words, with that tongue shout a victory ode.… You have mounted above heavens and the heavens of heavens and have taken your place at the royal throne itself. Accordingly, "Shout to God," that is, offer thanksgiving to him, the victory to him, the trophy to him. The conflict is not human or the battle physical, nor is the contest over any earthly concern but over the heavens and those in the heavens. He personally conducted this war and gave us a share in the victory.
On 46:2
When you hear that your Lord was impaled, that he was hanged on the cross, that he was buried, that he descended to the lower parts of the earth, do not be discouraged or troubled: he is most high, and by nature most high. What is most high by nature would never change its exaltation, nor would it become lowly; rather, even in his lowliness his exaltation remains and is revealed. For even in his dying he then most of all demonstrated his power over death. "The light shines in the darkness," Scripture says, "and the darkness did not overcome it." That was the way his elevation appeared in his lowliness.… At that time the sun diverted its rays, rocks were split, the veil torn, the earth disturbed, Judas expired, Pilate and his wife scared, the judge himself on the defensive. So when you hear that he was bound and scourged, do not be disturbed; rather, see him giving evidence of his might even in bondage. He said, "Whom do you seek?" and hurled them on their back. Do you see how he is fearsome, working such marvels by voice and nod alone?
On 46:2
This is really a great king, one who rids the world of error, and in a short space of time installs truth and abolishes the devil's tyranny, who was a great king even before there were subjects, having the might of his rule not in slaves, nor in pomp and circumstance but in nature itself.… This is a great king, the one whose dignity is not from without, who depends on no one for his kingship, who does all he wishes.… He chose his subjects in such a way as to persuade them to surrender their spirit rather than disregard what was commanded. Whereas the king enjoys the esteem of his subjects themselves, he by contrast provides the subjects with esteem; thus one is only a name, the other is reality. A great king is the one who made the whole world heaven, caused savages to have sound values and persuaded them to imitate angels.
On 46:4
What a marvel! He convinced those who crucified him to bow down in worship; those who mocked and blasphemed, those addicted to idol worship he taught to let their souls yield to his will. This transformation, you see, was not of the apostles' doing but done by him who led the way before them and moved their spirit. I mean, how could a fisherman or a builder have so changed the world had not the words of this person cleared all these obstacles? Sorcerers and tyrants and demagogues and philosophers and all their opponents they scared away like grains of dust and dissipated like smoke. In this way they spread the light of truth, employing not weapons or abundance of wealth but simple speech—or, rather, the speech was not simple but more potent than any action. So how? They called on the name of the crucified, and death skulked away, demons were put to flight, diseases were cured, bodily disfigurement righted, wickedness dispelled, dangers dissipated and the elements transformed.… He it was who removed the obstacles as he went before them; he himself smoothed out problems and made difficult things easy. And yet everything was beset by conflicts, everything with snares and hazards, no foothold or places to stand firm, all havens obstructed, every house shut, the ears of all stopped. Nevertheless, as soon as they entered and spoke, all strongholds of the enemy fell, with the result that they even surrendered their souls and then withstood countless dangers for the sake of what they had been told.
On 46:5
Someone may be bewildered and uncertain, and say, "So how is it that the Jews do not believe today?" … Listen to what follows; he added, "the beauty of Jacob, which he loved." Here in fact he seems to me to be referring to the believers, as Paul indicated in saying, "It is not, however, as though the word of God had failed: not all of Israel belong to Israel; … it is not the children of the flesh who are children of God, but the children of the promise who are counted as descendants." Now, the believers are rightly spoken of as the people's beauty; what could be more appealing, after all, than those who have come to faith?
Second Reading — Ephesians 1:17-23
Irenaeus
On 1:21
To these persons one may with justice say (as Scripture itself suggests), To what distance above God do ye lift up your imaginations, O ye rashly elated men? Ye have heard "that the heavens are meted out in the palm of [His] hand:" tell me the measure, and recount the endless multitude of cubits, explain to me the fulness, the breadth, the length, the height, the beginning and end of the measurement,-things which the heart of man understands not, neither does it comprehend them. For the heavenly treasuries are indeed great: God cannot be measured in the heart, and incomprehensible is He in the mind; He who holds the earth in the hollow of His hand. Who perceives the measure of His right hand? Who knoweth His finger? Or who doth understand His hand,-that hand which measures immensity; that hand which, by its own measure, spreads out the measure of the heavens, and which comprises in its hollow the earth with the abysses; which contains in itself the breadth, and length, and the deep below, and the height above of the whole creation; which is seen, which is heard and understood, and which is invisible? And for this reason God is "above all principality, and power, and dominion, and every name that is named," of all things which have been created and established. He it is who fills the heavens, and views the abysses, who is also present with every one of us. For he says, "Am I a God at hand, and not a God afar off? If any man is hid in secret places, shall I not see him?" For His hand lays hold of all things, and that it is which illumines the heavens, and lightens also the things which are under the heavens, and trieth the reins and the hearts, is also present in hidden things, and in our secret [thoughts], and does openly nourish and preserve us.
Wherefore he who had received the apostolate to the Gentiles, did labour more than those who preached the Son of God among them of the circumcision. For they were assisted by the Scriptures, which the Lord confirmed and fulfilled, in coming such as He had been announced; but here, [in the case of the Gentiles,] there was a certain foreign erudition, and a new doctrine [to be received, namely], that the gods of the nations not only were no gods at all, but even the idols of demons; and that there is one God, who is "above all principality, and dominion, and power, and every name which is named;" and that His Word, invisible by nature, was made palpable and visible among men, and did descend "to death, even the death of the cross;" also, that they who believe in Him shall be incorruptible and not subject to suffering, and shall receive the kingdom of heaven.
Gospel — Mark 16:15-20
Augustine of Hippo
On 16:19
(ubi sup.) By which words He seems to shew clearly enough that the foregoing discourse was the last that He spake to them upon earth, though it does not appear to bind us down altogether to this opinion. For He does not say, After He had thus spoken unto them, wherefore it admits of being understood not as if that was the last discourse, but that the words which are here used, After the Lord had spoken unto them, he was received into heaven, might belong to all His other discourses. But since the arguments which we have used above make us rather suppose that this was the last time, therefore we ought to believe that after these words, together with those which are recorded in the Acts of the Apostles, our Lord ascended into heaven.
On 16:19
(Epist. cxcix. 12.) (Acts 1:8) But how was this preaching fulfilled by the Apostles, since there are many nations in which it has just begun, and others in which it has not yet begun to be fulfilled? Truly then this precept was not so laid upon the Apostles by our Lord, as though they alone to whom He then spoke were to fulfil so great a charge; in the same way as He says, Behold, I am with you always, even unto the end of the world, apparently to them alone; but who does not understand that the promise is made to the Catholic Church, which though some are dying, others are born, shall be here unto the end of the world?
On 16:20
(de Symbolo, 4) Let us not therefore understand this sitting as though He were placed there in human limbs, as if the Father sat on the left, the Son on the right, but by the right hand itself we understand the power which He as man received from God, that He should come to judge, who first had come to be judged. For by sitting we express habitation, as we say of a person, he sat himself down in that country for many years; in this way then believe that Christ dwells at the right hand of God the Father. For He is blessed and dwells in blessedness, which is called the right hand of the Father; for all is right hand there, since there is no misery. It goes on: And they went forth and preached every where, the Lord working with than, and confirming the word with signs and wonders.
