Before Any Work
Bless, O Lord.
or
O Lord Jesus Christ, the Only-Begotten Son of Thine Eternal Father, Thou hast said, "Without me you can do nothing." In faith I embrace Thy words, O Lord, and bow before Thy goodness. Help me to complete the work I am about to begin for Thine own glory: In the name of Father, Son [+], and Holy Spirit. Amen.
After Any Work
Glory to Thee, O Lord.

Thou, O Christ, art Thyself the fulfillment of all good things. Fill my soul with joy and gladness, and save me, for Thou art all merciful.
