Act of Thanksgiving (Catholic Traditional Prayer)

I give Thee thanks, O Lord, from the bottom of my heart, for all the mercies and blessings which Thou hast bestowed upon me and on Thy whole Church through Jesus Christ Thy Son; above all, because Thou hast loved me from all eternity, and hast sent Thy Son to redeem me with His precious Blood. O let not that Blood be shed for me in vain. Amen.
