From the Holy Gospel according to John
John 19:31-37
At that time: The Jews, because it was the Preparation, that the bodies should not remain upon the cross on the Sabbath Day, for that Sabbath Day was an high day, besought Pilate that their legs might broken, and that they might be taken away. And so on.

A Homily by St. Augustine the Bishop
Tractatus 120 in Joannem, nn. 2-3
But when they came to Jesus, and saw that he was dead already, they brake not his legs: but one of the soldiers with a spear opened his side, and forthwith came there out blood and water. Note that the Evangelist maketh use of a word of special significance. He saith not: Penetrated his side: nor yet: Wounded: nor any other thing; but rather: Opened: that thereby in a sense the door of life might be thrown open, from whence the Sacraments of the Church have flowed forth, without which there is no entrance into the life which is the only true life. For that blood was shed for the remission of sins; and that water hath brought into being the life-giving flagon, which same is both the laver of Baptism and the cup that giveth refreshment to them that thirst. All this was announced long before, to wit, when Noah was commanded to make a door in the side of the ark, through which might enter all living creatures which were not destined to perish in the flood; and this same is a figure of the Church.

When the Lord, as we read in the Gospel, asked his disciples who did men, amid their diverse speculations, believe him the Son of Man to be, blessed Peter answered and said: Thou art the Christ, the Son of the living God. And the Lord answered and said unto him: Blessed art thou, Simon Bar-Jona: for flesh and blood hath not revealed it unto thee, but my Father, which is in heaven: and I say also unto thee: That thou art Peter, and upon this rock I will build my Church, and the gates of hell shall not prevail against it; and I will give unto thee the keys of the kingdom of heaven; and whatsoever thou shalt bind on earth shall be bound in heaven; and whatsoever thou shalt loose on earth shall be loosed in heaven. But the dispensation of truth perdures, and blessed Peter, persevering in the strength of the rock which he hath received, hath not relinquished the position he assumed at the helm of the Church.

From the Holy Gospel according to Luke
Luke 1:39-47
And Mary arose in those days and went into the hill-country with haste, into a city of Judah. And entered into the house of Zacharias, and saluted Elizabeth. And so on.

Homily by St. Ambrose, Bishop of Milan
Bk. ii Comm. on Luke i
We must here consider that the greater cometh unto the lesser, Mary unto Elizabeth, Christ unto John. And again afterwards, to hallow the baptism of John, the Lord came unto him to be baptized. It was soon that the blessings of the coming of Mary and of the Presence of God were made manifest. Have regard here to the distinction made, and to the special weight of every word. Elizabeth was the first to hear the voice of Mary's salutation, but John was the first to receive grace. She heard naturally, but he leaped mystically. She hailed the coming of Mary, he that of the Lord, Mary and Elizabeth spake words full of grace, but Jesus and John worked, and commenced their mystery of godliness from their mothers' beginnings, and so by twin miracles the mothers prophesied from the spirit of their unborn offspring. The babe leaped, and the mother was filled with the Holy Ghost. The mother was not filled before the son, but when the son was filled with the Holy Ghost, he filled his mother also.

From the Holy Gospel according to John
John 19:30-35
At that time: When Jesus had received the vinegar, He said: It is finished. And He bowed His Head, and gave up the ghost. And so on.

Homily by St. Augustine, Bishop of Hippo
120th Tract on John
One of the soldiers with a spear pierced His Side, and forthwith came thereout Blood and Water. The Evangelist speaketh carefully. He saith not that he smote the Side, nor yet that he wounded It, nor yet anything else, but pierced It, to fling wide the entrance unto life, whence flow the Sacraments of the Church, those Sacraments without which there is no entrance unto the life which is life indeed. That Blood which was shed there was shed for the remission of sins, that Water is the water that mantleth in the cup of salvation. Therein are we washed, and thereof do we drink. Of this was it a type when it was said unto Noah: The door of the ark shalt thou set in the side thereof and of every living thing of all flesh shalt thou bring into the ark to keep them alive. Gen. vi. 16, 19. A figure this of the Church. Thus was it that the first woman was made from the side of her husband while he slept, and she was called (Eve, which is, being interpreted,) Life, because she was the mother of all living. Gen. iii. 20. This name set forth a great good, before it became associated with the bitter fruit of a great evil. And here we have the Second Adam bowing His Head, and the deep sleep of death falling upon Him upon the Cross, and He sleepeth, that the Lord God may take a thing out of His side, and may make thereof a wife for Him. O what a death was His, which quickeneth the dead! What is cleaner than His Blood? What more health-giving than His wounding?

Matt 10:28-33
At that time: Jesus said unto his disciples: Fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell. And so forth.

A Homily by St. Irenaeus the Bishop and Martyr
Lib. 3 adversus Haereses cap. 18, alias 20, num. 5-6
The Lord knew both those who would suffer persecution; and he knew those who would be scourged and slain for his sake. His words are indeed those of exhortation: Fear not them which kill the body, but are not able to kill the soul. Rather fear him which hath power to cast both body and soul into hell, and to preserve whomsoever should confess him. For indeed he hath promised to confess before his Father those who should confess his name before men; and to deny those who should deny him, and to be ashamed of those who should be ashamed to confess him. Yet for all this, some have gone so far in audacity, as to scorn even the Martyrs, and to revile those who have been put to death for confessing the Lord, and who endure all that the Lord foretold, and so far endeavour to follow in the footsteps of the Lord's Passion, being made Martyrs of one who was capable of suffering; but these we leave to the Martyrs themselves. For when their blood shall be required, and they shall obtain glory, then all those who have dishonoured their martyrdom will be put to confusion by Christ.

At that time, Jesus said unto the multitudes of the Jews: My Flesh is meat indeed, and My Blood is drink indeed. And so on.

Homily by St. Hilary, Bishop of Poitiers.
Bk. viii. on the Trinity)
When we speak concerning the things of God, we must not speak after the manner of men, nor after the manner of the world. Let us read those things which are written, and understand those things which we read and then let us act as having a perfect faith. We shall speak but folly and godlessness if we speak concerning the natural truth of Christ in use and have not learnt at Christ's School how we should speak. He Himself saith “My Flesh is meat indeed, and My Blood is drink indeed. He that eateth My Flesh and drinketh My Blood, dwelleth in Me, and I in him.” There is here no room left for doubt as to What is His Flesh and what is His Blood.

From the Holy Gospel according to John

John 6:56-59

At that time, Jesus said unto the multitudes of the Jews: My Flesh is meat indeed, and My Blood is drink indeed. And so on.

Homily by St. Augustine, Bishop of Hippo.

26th Tract on John.

“This is the bread which cometh down from heaven,” v. 50. By “this bread” the Lord here signifieth both the manna, and That Which we receive at the Altar of God. Both these are, as it were, Sacramental signs, differing indeed somewhat in their outward and visible part, but pointing to the Same Thing signified. Hear what the Apostle saith: “Moreover, brethren, I would not that ye should be ignorant how that all our fathers were under the cloud, and all passed through the sea, and were all baptized unto Moses in the cloud and in the sea, and did all eat the same spiritual meat.” 1 Cor. x. 1-3. This meat was the same spiritually but not really they ate manna we eat Something else. Spiritually they ate What we eat but our fathers not their fathers; unto whom we are like not unto whom they are like. And it is added “And did all drink the same Spiritual drink.” They drank one thing, and we drank Another, the difference being in the outer show, the sameness in that the Same Thing is pointed to by both. And what was that Same Drink? “They drank of the spiritual Rock that followed them, and that Rock was Christ.” Him did bread and rock alike signify. The Rock was a figure, but by the Word and in the Flesh there is the very Christ Himself. And how came they to drink of that rock “Moses lift up his hand, and with his rod he smote the rock twice, and the water came out abundantly.” Num. xx. 11. These two strokes of the rod upon the rock are a figure of the two beams whereof the Cross was made.

Post Communion
P. The Lord be with you.
S. And with thy spirit.
Let us pray.
We beseech You, O Lord, that having received Your gifts, each partaking of this sacrament may increase within us its saving effects.
Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, God, world without end.
℟. Amen.

Let us pray.
Commemoration Vigil of the Nativity of St. John the Baptist
May the powerful prayer of blessed John the Baptist go with us, O Lord, and may he plead with our Lord Jesus Christ, Your Son, Whose coming he foretold, to be merciful unto us.
Who livest and reignest with God the Father, in the unity of the Holy Spirit, God, world without end.
℟. Amen
