O God, who in Thine ineffable Providence, hast sent Thy Holy Angels to watch over us: grant, we humbly pray, that we may always be defended by their protection and may rejoice in their fellowship forever. Through Christ our Lord. Amen.God our Father, in a wonderful way You guide the work of angels and men. May those who serve You constantly in Heaven keep our lives safe from all harm here on earth. 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. Amen
Father, in praising Your faithful angels and archangels, we also praise Your glory, for in honoring them, we honor You, their Creator. Their splendor shows us Your greatness, which surpasses in goodness the whole of creation. Amen.
Most noble Archangels, you who, under the command of St Michael, guard and protect the Holy Church, deign to deliver her from internal and external enemies. Watch over all the children of the Immaculate Spouse of Christ, and in virtue of the Divine Blood, obtain for us the grace to live and die in the Faith, Hope and Charity of Holy Church, so that we may be eternally united with its august Head, Jesus Christ, our Lord.
You Angels and Archangels, you Thrones and Dominations, you Principalities and Powers, you Virtues of the heavens, Cherubim and Seraphim, bless the Lord for ever . Amen
