Irenaeus was born in Smyrna, (now Izmir in Turkey) and emigrated to Lyons, in France, where he eventually be­came the bishop. Irenaeus fought against many heresies especially the Gnostics and Valentinians.

Entrance Antiphon: Mal 2: 6        

The law of truth was in his mouth; no dishonesty was found on his lips. He walked with me in integrity and peace, and turned many away from evil.


O God, who called the Bishop Saint Irenaeus to confirm true doctrine and the peace of the Church, grant, we pray, through his intercession, that, being renewed in faith and charity, we may always be intent on fostering unity and concord. Through our Lord Jesus Christ, your Son, who lives and reigns with you in the unity of the Holy Spirit, one God, for ever and ever.

First reading: Genesis 15: 1-12, 17-18

It happened that the word of the Lord was spoken to Abram in a vision, “Have no fear, Abram, I am your shield; your reward will be very great.”  “My Lord,” Abram replied, “what do you intend to give me? I go childless…” Then Abram said, “See, you have given me no descendants; some man of my household will be my heir.” And then this word of the Lord was spoken to him, “He shall not be your heir; your heir shall be of your own flesh and blood.” Then taking him outside he said, “Look up to heaven and count the stars if you can. Such will be your descendants” he told him. Abram put his faith in the Lord, who counted this as making him justified.  “I am the Lord,” he said to him, “who brought you out of Ur of the Chaldaeans to make you heir to this land.” “My Lord,” Abram replied, “how am I to know that I shall inherit it?” He said to him, “Get me a three-year-old heifer, a three-year-old goat, a three-year-old ram, a turtledove and a young pigeon.” He brought him all these, cut them in half and put half on one side and half facing it on the other; but the birds he did not cut in half. Birds of prey came down on the carcases but Abram drove them off. Now as the sun was setting Abram fell into a deep sleep, and terror seized him. When the sun had set and darkness had fallen, there appeared a smoking furnace and a firebrand that went between the halves. That day the Lord made a Covenant with Abram in these terms: “To your descendants I give this land, from the wadi of Egypt to the Great River, the river Euphrates.”

Psalm 104 (105): 1-4, 6-9

R/ The Lord remembers his covenant for ever.

Give thanks to the Lord, tell his name, make known his deeds among the peoples. O sing to him, sing his praise; tell all his wonderful works!

Be proud of his holy name, let the hearts that seek the Lord rejoice. Consider the Lord and his strength; constantly seek his face.

O children of Abraham, his servant, O sons of the Jacob he chose. He, the Lord, is our God:  his judgements prevail in all the earth.

He remembers his covenant forever, his promise for a thousand generations, the covenant he made with Abraham, the oath he swore to Isaac.

Gospel Acclamation: Ps 118: 18

Alleluia, alleluia! Open my eyes, O Lord, that I may consider the wonders of your law. Alleluia!

Gospel: Matthew 7:15-20 

Jesus said to his disciples: “Beware of false prophets who come to you disguised as sheep but underneath are ravenous wolves. You will be able to tell them by their fruits. Can people pick grapes from thorns, or figs from thistles? In the same way, a sound tree produces good fruit but a rotten tree bad fruit. A sound tree cannot bear bad fruit, nor a rotten tree bear good fruit. Any tree that does not produce good fruit is cut down and thrown on the fire. I repeat, you will be able to tell them by their fruits.”

Prayer over the Offerings 

May the sacrifice we offer you with joy on the heavenly birthday of Saint Irenaeus bring you glory, O Lord, and instil in us a love of the truth, so that we may keep the Church’s faith inviolate and her unity secure. Through Christ our Lord.

Communion Antiphon: Jn 15: 4-5           

Remain in me, as I remain in you, says the Lord. Whoever remains in me, and I in him, bears fruit in plenty.

Prayer after Communion 

Through these sacred mysteries, we pray, O Lord, give us in your compassion an increase of that faith which brought glory to the Bishop Saint Irenaeus as he maintained it even until death, and may the same faith bring to us, who truly follow it, justification in your sight. Through Christ our Lord.


“Beware of false prophets. Jesus’ statements on this theme are so simple that they sound simplistic. But they are not at all! Men are recognised by their fruits. Many are seductive with their beautiful words. Today, many voices claim to be from the Lord our God, but they do not sound the same; we are lost in wondering on who is a false prophet and who is a true prophet, even if unusual things are done by many of them. May the Lord help us to be less attentive to their words than to their fruits, in order to recognise those who truly speak in the name of Jesus Christ our Saviour.
