I asked in prayer for love of Christ,
Whitsunday, &
Consecration of Priests to the Holy SpiritCOME, HOLY SPIRIT COME!
I give thanks to my God always on your account for the grace of God bestowed on you in Christ Jesus, that in him you were enriched in every way, with all discourse and all knowledge,
as the testimony to Christ was confirmed among you, so that you are not lacking in any spiritual gift as you wait for the revelation of our Lord Jesus Christ.
He will keep you firm to the end, irreproachable on the day of our Lord Jesus (Christ). God is faithful, and by him you were called to fellowship with his Son, Jesus Christ our Lord.
Let us pray.
Come, Holy Spirit, fill the hearts of Thy faithful and enkindle in them the fire of Thy love. Send forth Thy Spirit and they shall be created. And Thou shalt renew the face of the earth.
O God, Who didst instruct the hearts of the faithful by the light of the Holy Spirit, grant us in the same Spirit to be truly wise, and ever to rejoice in His consolation. Through Christ our Lord. Amen.
(My favorite -I don't know the author)
O Holy Spirit, love of the Father and of the Son be as a furnace of love in the center of our hearts and ever bear like glowing flames, our thoughts, our affections, our actions on high, even unto the bosom of the Father. May our whole lives be a Glory Be to the Father, to the Son, and to the Holy Spirit. Amen.
