The sacrifice isn't literal, for everyone. JESUS is a GOD, and the sacrifice is for those who worship Him, as a GOD.
JESUS's human form is mystical, and people percieved Him as fully human, even though He was doing things, that no human can do.
JESUS was always a God, hence the worship as He was in Israel. JESUS went elsewhere, in His God form, and this is why He left Israel, after the ascencion.
The baptism by Jesus is completely different from the baptism, for redemption, and this is noted many times in the NT.
There is no baptism parallel in the churches, and they simply inquire, or in the name of, to symbolize the actual baptism, by Jesus, which may or may not occur, at time of church baptism.
As a God, JESUS is beyond historical apologetics and speculation, and that is where the churches and such encounter most of their contradictions, so forth.
The cross is a symbol used for the followers of JESUS, and is not actually representive of the crucifixion, because previous to the crucifixion, JESUS said take up your cross, to His followers. This was a symbol, not a metaphor of crucifixion. That is why the 'empty cross', is the most traditional cross for JESUS followers.
Last time I checked, he was, according to Christians, truly God and truly man (I disagree, but whatever). *IF* Christians do in fact believe he is truly man, then they really need to explain away the problem of human sacrifice. It doesn't go away by saying he is God as well.
What I wrote, there, is a non'literal Sacrifice perspective.
