545 O holy, blessed Trinity,

1 O holy, blessed Trinity, Divine, essential Unity, God, Father, Son, and Holy Ghost, Be Thou this day my guide and host. 2 My soul and body keep from harm, O'er all I have extend Thine arm, That Satan may not cause distress, Nor bring me shame and wretchedness. 3 The Father's love shield me this day, The Son's pure wisdom cheer my way, The Holy Spirit's light divine Illume my heart's benighted shrine. 4 My Maker, strengthen Thou my heart, O my Redeemer, help impart, Blest Comforter, keep at my side, That faith and love in me abide. 5 Lord, bless and keep Thou me as Thine! Lord, make Thy face upon me shine! Lord, lift Thy countenance on me, And give me peace, sweet peace from Thee.
