The Most Holy Trinity | St. Richard of Chichester (1197 – 1253)
Entrance Antiphon
Blest be God the Father, and the Only Begotten Son of God, and also the Holy Spirit, for he has shown us his merciful love.
Collect
God our Father, who by sending into the world the Word of truth and the Spirit of sanctification made known to the human race your wondrous mystery, grant us, we pray, that in professing the true faith, we may acknowledge the Trinity of eternal glory and adore your Unity, powerful in majesty. 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: Deuteronomy 4:32-34,39-40
Moses said to the people: ‘Put this question to the ages that are past, that went before you, from the time God created man on earth: Was there ever a word so majestic, from one end of heaven to the other? Was anything ever heard? Did ever a people hear the voice of the living God speaking from the heart of the fire, as you heard it, and remain alive? Has any god ventured to take to himself one nation from the midst of another by ordeals, signs, wonders, war with mighty hand and outstretched arm, by fearsome terrors – all this that the Lord your God did for you before your eyes in Egypt? ‘Understand this today, therefore, and take it to heart: the Lord is God indeed, in heaven above as on earth beneath, he and no other. Keep his laws and commandments as I give them to you today, so that you and your children may prosper and live long in the land that the Lord your God gives you for ever.’
Psalm 32(33):4-6,9,18-20,22
R/ Happy the people the Lord has chosen as his own.
1. For the word of the Lord is faithful and all his works to be trusted. The Lord loves justice and right and fills the earth with his love.
2. By his word the heavens were made, by the breath of his mouth all the stars. He spoke; and it came to be. He commanded; it sprang into being.
3. The Lord looks on those who revere him, on those who hope in his love, to rescue their souls from death, to keep them alive in famine.
4. Our soul is waiting for the Lord. The Lord is our help and our shield. May your love be upon us, O Lord, as we place all our hope in you.
Second reading: Romans 8:14-17
Everyone moved by the Spirit is a son of God. The spirit you received is not the spirit of slaves bringing fear into your lives again; it is the spirit of sons, and it makes us cry out, ‘Abba, Father!’ The Spirit himself and our spirit bear united witness that we are children of God. And if we are children we are heirs as well: heirs of God and co-heirs with Christ, sharing his sufferings so as to share his glory.
Gospel Acclamation: cf.Rv1:8
Alleluia, alleluia! Glory be to the Father, and to the Son, and to the Holy Spirit; the God who is, who was, and who is to come. Alleluia!
Gospel: Matthew 28:16-20
The eleven disciples set out for Galilee, to the mountain where Jesus had arranged to meet them. When they saw him they fell down before him, though some hesitated. Jesus came up and spoke to them. He said, ‘All authority in heaven and on earth has been given to me. Go, therefore, make disciples of all the nations; baptise them in the name of the Father and of the Son and of the Holy Spirit, and teach them to observe all the commands I gave you. And know that I am with you always; yes, to the end of time.’
Prayer over the Offerings
Sanctify by the invocation of your name, we pray, O Lord our God, this oblation of our service, and by it make of us an eternal offering to you. Through Christ our Lord.
Communion Antiphon: Gal 4: 6
Since you are children of God, God has sent into your hearts the Spirit of his Son, the Spirit who cries out: Abba, Father.
Prayer after Communion
May receiving this Sacrament, O Lord our God, bring us health of body and soul, as we confess your eternal holy Trinity and undivided Unity. Through Christ our Lord.
Meditation
We celebrate with joy today the Holy Trinity as we encounter the inner mystery of God as a family of persons, Father, Son and Holy Spirit, where there is complete harmony, love and total peace. It is a celebration that calls all Christians to ensure that they become ambassadors of unity and peace. It is also a call to go on mission as Jesus mandated us to do. The Holy Trinity is at work in us from the moment of our baptism and as we have been sent, we are to teach a sound doctrine and live by good example, for Jesus is always with us till the end.
