The holy card depicts the elevation of the sacred Host after the consecration, with Christ crucified mystically present and server and people kneeling before the altar. On the back Fr. Venantius wrote a prayer, which I transcribe as best I can, though I can't make out the whole thing. I don't know if this is his composition or if it's from somewhere else. If anyone knows, speak up.
When at the words of Consecration
My eyes look through my Savior's Blood,
Lo! in the chalice's shimmering gold
Mirrored my image I behold!
My heart is crushed with consternation
And weeps and sigh: My Lord, My God,
Thy Sacred Blood be my salvation!
Oh! grant that this poor heart of mine
Be henceforth modeled after Thine!
Thy...[?]...in me perfect,
Which my whole being must reflect.
So when at Holy Consecration
My eyes look through they Precious Blood,
There on the bottom's shimmering gold
A Christ-like priest I may behold!
