Thanksgiving to the Trinity
This lovely prayer is Act of Thanksgiving to the Trinity, from St. Catherine's Dialogue on Divine Providence.
It appears in the Office of the Readings on her feast day, April 29.
O Eternal God! O Eternal Trinity! Through the union of Thy divine nature Thou hast made
so precious the Blood of Thine only-begotten Son! O eternal Trinity, Thou art as deep a
mystery as the sea, in whom the more I seek, the more I find; and the more I find, the more
I seek. For even immersed in the depths of Thee, my soul is never satisfied, always

O eternal Trinity, with the light of understanding I have tasted and seen the depths of Thy
mystery and the beauty of Thy creation. In seeing myself in Thee, I have seen that I will
become like Thee. O eternal Father, from Thy power and Thy wisdom clearly Thou hast

Thou givest me then Thy very Self? Thou art a fire that burns eternally yet never

fire who taketh away all cold heartedness and illuminateth the mind by Thy light, the light
with which Thou hast made me to know Thy truth.
By this mirrored light I know Thou are the highest good, a good above all good, a fortunate
good, an incomprehensible good, an unmeasurable good, a beauty above all beauty, a
wisdom above all wisdom, for Thou art wisdom itself, the the food of angels, the fire of love

Thou art the garment covering our nakedness. Thou feedest our family with Thy sweetness,
a sweetness Thou art from which there is no trace of bitterness. O Eternal Trinity! Amen.
