Continuation of the Holy Gospel according to John

John 3:16-21
At that time, Jesus said unto Nicodemus: God so loved the world that He gave His Only-begotten Son, that whosoever believeth in Him should not perish, but have everlasting life. And so on.

Homily by St. Augustine, Bishop of Hippo
12th Tract on John
The Physician cometh that, as often as in him lieth, he may heal the sick man. He is his own destroyer who will not keep the commandments of the Physician. Into the world came the Saviour. Why is He called the Saviour of the world, but because He came “into the world not to condemn the world, but that the world through Him might be saved”? If thou willest not be saved through Him, thou wilt be condemned of thyself. And why say I that thou wilt be condemned? Because it is written: “He that believeth in Him is not condemned.” What then canst thou hope that He will say of “him that believeth not,” but that He will be condemned And indeed He doth say farther: “He that believeth not is condemned already.” He is condemned already, though the condemnation be not yet openly pronounced.

Homily by Pope St. Gregory the Great
30th on the Gospels
Dearly beloved brethren, our best way will be to run briefly through the words which have been read from the Holy Gospel, and thereafter rest for a while quietly gazing upon the solemn subject of this great Festival. This is the day whereon “suddenly there came a sound from heaven,” and the Holy Ghost descended upon the Apostles, and, for fleshly minds, gave them minds wherein the love of God was shed abroad and, while without “there appeared unto them cloven tongues, like as of fire, and it sat upon each of them,” within, their hearts were enkindled. While they received the visible presence of God in the form of fire, the flames of His love enwrapped them. The Holy Ghost Himself is love whence it is that John saith “God is love.” Whosoever therefore loveth God with all his soul, already hath obtained Him Whom he loveth, for no man is able to love God, if He have not gained Him Whom he loveth.

At that time, Jesus said to His disciples, If you love Me, keep My commandments. And I will ask the Father and He will give you another Advocate to dwell with you forever, the Spirit of truth Whom the world cannot receive, because it neither sees Him nor knows Him. But you shall know Him, because He will dwell with you, and be in you. I will not leave you orphans: I will come to you. Yet a little while and the world no longer sees Me. But you see Me, for I live and you shall live. In that day you will know that I am in My Father, and you in Me, and I in you. He who has My commandments and keeps them, he it is who loves Me. But he who loves Me will be loved by My Father, and I will love him and manifest Myself to him.

From the Treatise upon the Creed, addressed to Catechumens by St. Augustine, Bishop of Hippo
Bk. iv. ch. I. tom. 9
We are yet the unborn offspring of a great Mother. Our Holy Mother the Church hath by the most sacred sign of the Cross received you into her womb, and from thence she is now just about to bring you forth, as she hath already brought forth your brethren, with thrills of spiritual joy. But until, through the washing of regeneration, she bringeth you forth into true light, she feedeth you in her womb with such food as becometh your condition, and in gladness matureth her children for the glad moment of her delivery. This Mother is not stricken by the doom of Eve, to bring forth children in sorrow, and they themselves oftenertimes weeping than laughing. Rather doth your spiritual Mother annul the sentence of your earthly Eve, by disobedience, endowed her offspring with death the Church, by obedience, giveth them newness of life. All the mystic prayers and ceremonies which have been and are still being performed over you by the ministry of the servants of God, exorcisms, prayers, spiritual songs, onbreathings, haircloth, prostrations, baring of the feet, the dread which ye feel, albeit so safe, all these things, I say unto you, are the nourishment which ye are ever. drawing from your Mother while yet ye are in her womb, that at the baptismal birth she may be able to present you strong and laughing babes unto Christ.

We have also received the Creed, which is the shield of the travailing Mother against the venom of the dragon. In the Apocalypse of the Apostle John xii. 4 it is written “And the dragon stood before the woman which was ready to be delivered, for to devour her child as soon as it was born.” That this dragon is the devil ye all know. Ye know likewise that by the woman is signified the Virgin Mary, who, herself a Virgin, bore our Virgin Head, and who is revealed unto us as a type of the Holy Church, in that, even as Mary, though she bore a Son, remained a Virgin, so the Church doth in all times give birth to all her members, and yet is ever presented a chaste virgin to Christ. I have undertaken, with the help of the Lord, to expound every clause of the Creed, that I may bring home to your understandings what each containeth. Your hearts are ready, for the enemy hath been shut out of your hearts.

We have made profession of renouncing the enemy. At the moment of that profession it was not before men only, but in the presence of God and His Angels that ye said: “I do renounce him.” Renounce him, not only in your words, but in your ways not only with your voices, but with your lives not only with your lips, but in your works. Know ye well that the wrestling which ye have undertaken is a strife with an enemy who is subtle, and old, and patient now that ye have once renounced him, let him never again find in you his works never again give him the right to bring you into bondage. O Christian thou wilt be caught and exposed, if thou dost one thing and professest another, if thou art faithful in name, and makest it to be evident by thy works that thou hast broken the faith pledged by this promise if some while thou goest into a church to pray, and anon to the shows to join in applauding obscene representations. What hast thou to do any more with the pomps of the devil, which thou hast renounced?

92nd Tract on John.
Upon the day of Pentecost the Holy Ghost came down upon a congregation of an hundred and twenty men, among whom were all the Apostles. These men, after they had been filled with the Spirit, began to speak with the tongues of all nations, and many of the bystanders, amazed at the marvel, when they saw in the discourse of Peter, how great and how Divine a witness was borne to the fact that the Christ, Whom they had murdered, and Whom they reckoned among the dead, had risen again and was alive, many of these bystanders were pricked in their heart Acts ii. 37 and were converted. They received pardon from that noble Blood, Which they had so sacrilegiously and so brutally shed, seeing that that Blood had redeemed even Its Own out-pourers.

The Prophet Habakkuk also hath spoken of the glory of Christ's Ascension in the words “The sun was lifted up on high, and the moon stood still in her habitation,” Who is here signified by the Sun, if not the Saviour or by the Moon, if not the Church? Until the Lord was withdrawn from her sight, (that is, by His Ascension,) His Holy Church was pale before the hostile glare of the world, but after He was ascended, she waxed stronger, and distinctly shed forth the beams of that faith which had hitherto dwelt hiddenly in her. “The sun was lifted up, and the moon stood still in her habitation” when the Lord was gone away into heaven, His holy Church waxed stronger in her enlightening power.

Dearly beloved brethren, the words of the Holy Gospel, which have just been read, lie open before you, and, lest their very plainness should make them seem to some to be hard, we will go through them with such shortness as that neither may they which understand not remain unenlightened, nor they which understand be wearied. The Lord saith Let your loins be girded about. Now, we gird our loins about, when by continency we master the lustful inclination of the flesh. But, forasmuch as it sufficeth not for a man to abstain from evil deeds, if he strive not to join thereto the earnest doing of good works, it is immediately added And your lights burning. Our lights burn when, by good works, we give bright example to our neighbour; concerning which works the Lord saith Let your light so shine before men, that they may see your good works, and glorify your Father Which is in heaven. Matth. v. 16.

Matt 16:13-19
At that time: When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am? And so on.

A Homily by St. Leo the Pope
Sermo 2 in anniversario assumpt. suæ ante medium
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.

Commemoration of: St. Pudentiana, Virgin
The maiden Pudentiana was the orphan daughter of Pudens the Roman Senator. She was a Christian of eminent godliness. She with her sister Praxedes distributed to the poor the money which they obtained by the sale of their inheritance. She gave herself continually to fasting and prayer. By her care the whole of the household, being ninety-six persons, were baptized by Pope Pius. Whereas the Emperor Antonine had forbidden the Christians to offer sacrifice in public, Pope Pius used to meet with them in Pudentiana's house, to celebrate the holy rites. She was a gracious hostess to them, and ministered to them in such things as are needful for the body. She thus busied herself in works of Christian godliness until she passed from this present life to a better. She was buried in her father's sepulchre in the cemetery of Priscilla on the Salarian Way upon the 19th day of May. (Breviarium Romanum.)

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.
