First Reading — Acts 4:8-12
Cyprian
On 4:8
That Christ also is called a Stone. In Isaiah: "Thus saith the Lord, Behold, I place on the foundations of Sion a precious stone, elect, chief, a corner stone, honourable; and he who trusteth in Him shall not be confounded." Also in the cxviith Psalm: "The stone which the builders rejected, the same is become the head of the corner. This is done by the Lord, and it is wonderful in our eyes. This is the day, which the Lord hath made; let us rejoice and be glad in it. O Lord, save therefore, O Lord, direct therefore. Blessed is He who cometh in the name of the Lord." Also in Zechariah: "Behold, I bring forth my servant. The Orient is his name, because the stone which I have placed before the face of Jesus; upon that one stone are seven eyes." Also in Deuteronomy: "And thou shall write upon the stone all this law, very plainly." Also in Jesus the son of Nave: "And be took a great stone, and placed it there before the Lord; and Jesus said unto the people, Behold, this stone shall be to you for a testimony, because it hath heard all the things which were spoken by the Lord, which He hath spoken to you to-day; and it shall be for a testimony to you in the last of the days, when ye shall have departed from your God." Also in the Acts of the Apostles, Peter: "Ye princes of the people, and elders of Israel, hearken: Behold, we are this day interrogated by you about the good deed done to the impotent man, by means of which he is made whole. Be it known unto you all, and to all the people of Israel, that in the name of Jesus Christ of Nazareth, whom ye have crucified, whom God hath raised up from the dead, by Him he stands whole in your presence, but by none other. This is the stone which was despised by you builders, which has become the head of the corner. For there is no other name given to men under heaven in which we must be saved." This is the stone in Genesis, which Jacob places at his head, because the head of the man is Christ; and as he slept he saw a ladder reaching to heaven, on which the Lord was placed, and angels were ascending and descending. And this stone he designating Christ consecrated and anointed with the sacrament of unction. This is the stone in Exodus upon which Moses sate on the top of a hill when Jesus the son of Nave fought against Amalek; and by the sacrament of the stone, and the stedfastness of his sitting, Amalek was overcome by Jesus, that is, the devil was overcome by Christ. This is the great stone in the first book of Kings, upon which was placed the ark of the covenant when the oxen brought it back in the cart, sent back and returned by the strangers. Also, this is the stone in the first book of Kings, with which David smote the forehead of Goliath and slew him; signifying that the devil and his servants are thereby thrown down-that part of the head, namely, being conquered which they have not had sealed. And by this seal we also are always safe and live. This is the stone which, when Israel had conquered the aliens, Samuel set up and called its name Ebenezer; that is, the stone that helpeth.
Responsorial Psalm — Psalm 118:1, 8-9, 21-23, 26, 28, 29
Clement of Rome
On 117:19–20
Let us therefore root this out quickly, and let us fall down before the Master and entreat him with tears, that he may show himself propitious and be reconciled to us and may restore us to the seemly and pure conduct that belongs to our love of the brothers. For this is a gate of righteousness opened to life, as it is written: "Open to me the gates of righteousness, that I may enter in thereby and praise the Lord. This is the gate of the Lord; the righteous shall enter in thereby." Seeing then that many gates are opened, this is that gate that is in righteousness, even that which is in Christ, whereby all are blessed who have entered in and direct their path in holiness and righteousness, performing all things without confusion. Let a person be faithful, let him be able to expound a deep saying, let him be wise in the discernment of words, let him be strenuous in deeds, let him be pure; for so much the more ought he to be lowly in mind, in proportion as he seems to be the greater; and he ought to seek the common advantage of all, and not his own.
Second Reading — 1 John 3:1-2
Clement of Alexandria
On 3:1
"For the world knows us not, as it knew Him not." He means by the world those who live a worldly life in pleasures.
On 3:2
"Beloved," says he, "now are we the sons of God," not by natural affection, but because we have God as our Father. For it is the greater love that, seeing we have no relationship to God, He nevertheless loves us and calls us His sons. "And it has not yet appeared what we shall be;" that is, to what kind of glory we shall attain. "For if He shall be manifested,"— that is, if we are made perfect, — "we shall be like Him," as reposing and justified, pure in virtue, "so that we may see Him" (His countenance) "as He is," by comprehension.
Gospel — John 10:11-18
John Chrysostom
On 10:12
(Hom. lx. 5) Our Lord shews here that He did not undergo His passion unwillingly; but for the salvation of the world. He then gives the difference between the shepherd and the hireling: But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth.
On 10:14
(Hom. lx. 1) Two evil persons have been mentioned, one that kills, and robs the sheep, another that doth not hinder: the one standing for those movers of seditions; the other for the rulers of the Jews, who did not take care of the sheep committed to them. Christ distinguishes Himself from both; from the one who came to do hurt by saying, I am come that they might have life; from those who overlook the rapine of the wolves, by saying that He giveth His life for the sheep. Wherefore He saith again, as He said before, I am the good Shepherd. And as He had said above that the sheep heard the voice of the Shepherd and followed Him, that no one might have occasion to ask, What sayest Thou then of those that believe not? He adds, And I know My sheep, and am known of Mine. (Rom. 11:12) As Paul too saith, God hath not cast away His people, whom He foreknew.
On 10:14
(Hom. lx. 1) He gives it too as a proof of His authority. In the same way the Apostle maintains his own commission in opposition to the false Apostles, by enumerating his dangers and sufferings.
On 10:15
(Hom. lx. 1) Then that thou mayest not attribute to the Shepherd and the sheep the same measure of knowledge, He adds, As the Father knoweth Me, even so know I the Father: i. e. I know Him as certainly as He knoweth Me. This then is a case of like knowledge, the other is not; as He saith, No man knoweth who the Son is, but the Father. (Luke 10:23)
On 10:16
(Hom. lx. 2) What wonder that these should hear My voice, and follow Me, when others are waiting to do the same. Both these flocks are dispersed, and without shepherds; for it follows, And they shall hear My voice. And then He foretells their future union: And there shall be one fold and one Shepherd.
On 10:17
(Hom. lx) The word must here (I must bring) does not signify necessity, but only that the thing would take place. Therefore doth My Father love Me, because I lay down My life, that I might take it again. They had called Him an alien from His Father.
On 10:18
(Hom. lx. 2) Or He says, in condescension to our weakness, Though there were nothing else which made Me love you, this would, that ye are so loved by My Father, that, by dying for you, I shall win His love. Not that He was not loved by the Father before, or that we are the cause of such love. For the same purpose He shews that He does not come to His Passion unwillingly: No man taketh it from Me, but I lay it down of Myself.
On 10:18
(Hom. lx. 2) As they had often plotted to kill Him, He tells them their efforts will be useless, unless He is willing. I have such power over My own life, that no one can take it from Me, against My will. This is not true of men. We have not the power of laying down our own lives, except we put ourselves to death. Our Lord alone has this power. And this being true, it is true also that He can take it again when He pleases: And I have power to take it again: which words declare beyond a doubt a resurrection. That they might not think His death a sign that God had forsaken Him, He adds, This commandment have I received from My Father; i. e. to lay down My life, and take it again. By which we must not understand that He first waited to hear this commandment, and had to learn His work; He only shows that that work which He voluntarily undertook, was not against the Father’s will.
