Feria IV of Sunday XVII Post Pentecost: Missa “Iustus es, Domine”
The liturgy reminds us today of the great commandment of charity towards God and our neighbor. “The precept is twofold,” declares St. Augustine, “but charity is one.” We love God above all and our neighbor for His sake. The unity of our faith, like the unity of the Persons of the Most Holy Trinity is the message of the Epistle and the Gospel imposes on us the duty of being united in the bonds of charity.
INTROIT Psalm 118:137; 118:124
You are just, O Lord, and Your ordinance is right. Deal with Your servant according to Your kindness. Happy are they whose way is blameless, who walk in the law of the Lord. V. Glory be to the Father, and to the Son, and to the Holy Ghost. R. As it was in the beginning, is now, and ever shall be, world without end. Amen
COLLECT
Grant, we beseech You, O Lord, that Your people may avoid the temptations of the devil, and with pure minds follow You, the only God. Through Jesus Christ, thy Son our Lord, Who liveth and reigneth with thee, in the unity of the Holy Ghost, ever one God, world without end.
R. Amen.

Through the same Jesus Christ, thy Son, Our Lord, Who liveth and reigneth with thee in the unity of the Holy Ghost, God, world without end.

EPISTLE Ephesians 4:1-6
Lesson from the letter of St Paul the Apostle to the Ephesians. Brethren: I, the prisoner in the Lord, exhort you to walk in a manner worthy of the calling with which you were called, with all humility and meekness, with patience, bearing with one another in love, careful to preserve the unity of the Spirit in the bond of peace: one body and one Spirit, even as you were called in one hope of your calling; one Lord, one faith, one Baptism, one God and Father of all, Who is above all, and throughout all, and in us all, Who is blessed forever and ever. Amen.
GRADUAL/ALLELUIA Psalm 32:12; 32:6
Happy the nation whose God is the Lord, the people the Lord has chosen for His own inheritance. V. By the word of the Lord the heavens were made; by the breath of His mouth all their host. Alleluia, alleluia. Ps 101:2 V. O Lord, hear my prayer, and let my cry come to You. Alleluia.
GOSPEL Matt 22:34-46
At that time, the Pharisees came to Jesus and one of them, a doctor of the Law, putting Him to the test, asked Him, Master, which is the great commandment in the Law? Jesus said to him, ‘You shall love the Lord your God with your whole heart, and with your whole soul, and with your whole mind.’ This is the greatest and first commandment. And the second is like it, ‘You shall love your neighbor as yourself.’ On these two commandments depend the whole Law and the Prophets. Now while the Pharisees were gathered together, Jesus questioned them, saying, What do you think of the Christ? Whose son is He? They said to Him, David’s. He said to them, How then does David in the spirit call Him Lord, saying, The Lord said to my Lord: Sit at My right hand, till I make Your enemies Your footstool?’ If David, therefore, calls Him ‘Lord,’ how is He his son? And no one could answer Him a word; neither did anyone dare from that day forth to ask Him any more questions.
OFFERTORY ANTIPHON Daniel 9:17-19

It is truly meet and just, and profitable unto salvation, that we should at all times, and in all places, give thanks to thee, O Holy Lord, Father Almighty, eternal God, through Christ, our Lord. Though whom the angels praise thy majesty, the dominions adore it, the powers are in awe. Which the heavens and the hosts of heaven together with the blessed seraphim joyfully do magnify. And do thou command that it be permitted to us join with them in confessing thee, while we say with lowly praise:
