Today I prayed the Mass in the back of the Sacramentary titled "For Priests" - it has some gems! Consider offering one or some of these prayers for all priests today if you get the chance.
Antiphon: The Spirit of God is upon me; he has anointed me. He sent me to bring good news to the poor, and to heal the broken-hearted." Lk. 4:18
Opening Prayer: Father, you have appointed your Son Jesus Christ eternal High Priest. Guide those he has chosen to be ministers of word and sacrament and help them to be faithful in fulfilling the ministry they have received. Grant this through our Lord Jesus Christ, your Son, who lives and reigns with you and the Holy Spirit, one God, for ever and ever
Prayer over the Gifts: Father, in your plan of salvation you have appointed priests to minister to your people at your holy altars. By the power of this sacrament may their priestly service always be pleasing to you and bring lasting good to your Church. We ask this through Christ our Lord.
Communion antiphon: Father, make them holy in the truth. As you sent me into the world, I have sent them into the world. John 17:17-18
Prayer after Communion: Lord, may the sacrifice we offer and receive give life to your priests and all your people. Keep them joined to you by a love that will never end, and make them worthy members of your household. We ask this in the name of Jesus the Lord.
