For our discussion........
On to the subject at hand, I do think the shedding of His Blood is quite a bit different than the fetid business of hawing his foreskin. For God's sake, I feel like hurling just writing that sentence!
"Take this cup, and drink of it, for this is my Blood." The shedding of Christ's Blood, that is, the Blood itself is very significant, in and of itself, though I do agree that it was His Death that was redemptive.
