"Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator." Galations 3:19 KJV
In light of all the debates about the teachings of Jesus that have escalated into numerous debates, lets settle this. Firstly, it is stated in the verse above that the laws of the old testament were ordained by angels, not the one true God in TOTAL contradiction to the Torah.
Secondly, Jesus Himself had stated that the god that the "father" that the Pharisees were worshipping was none other than Satan himself. (not to mention that Jesus said that there would be a time when the Temple would not even have one stone left stacked upon another.)
Thirdly, animal sacrifice and circumcision cannot be justified in light of Christ's teachings. If the "saints" of the Tanakh were redeemed by looking forward to Christ's sacrifice, why did they need to sacrifice animals? How does the sacrifice of animals cover sin?
The legitimacy of infant circumcision makes no sense, as it is forced unto a non consenting child, and therefore not a genuine act of conversion to faith. The same can be said for infant baptism in the Catholic church, but circumcision is worse in that it was obviously a residing tradition to "stabilize" the male population in tribal society without straight up child sacrifice to the Inverted Saturn.
