Act of Adoration
from the Small Roman Missal

O Great God, the Sovereign Lord of heaven and earth, I prostrate myself before Thee. With all the Angels and Saints I adore Thee, I acknowledge Thee to be my Creator and Sovereign Lord, my first beginning and last end. I render to Thee the homage of my being and life. I submit myself to Thy holy Will, and I devote myself to Thy divine service this day and for ever.
