If you don't believe this you have fallen into Nestorianism,DR E
The Infant Christ was not separated from the Hypostatic union ,DR E, He knew of the Crucifixion ,even all your sins and mine.
From the late FR William Most...
"His human soul saw the vision of divinity from conception, in which He knew all He would suffer. Lk 2:52 saying He grew in wisdom refers to the manifestation, not to an actual growth. Mk 13:32 tells us the source of His knowledge of the day was not His humanity, even though the day did register in His humanity."-FR William Most
For Roman Catholic apologists to say every drop of blood the Christ child shed when He cut His finger learning to be a carpenter, along with the blood the infant Jesus lost when He was circumcised, all go towards saving sinners is idolatry.
Salvation is spiritual (which may be why the papacy cannot understand it.) God's grace was bestowed on mankind at Calvary. Not in the woodshed learning how to hollow out a bowl for lunch.
And this sad superstition simply works toward infantilizing (thanks NL, although the word still comes up as misspelled) the Savior, Jesus Christ, while elevating the creature, Mary.
