Does God require a sacrifice as in the slaying of an innocent before he will forgive?
No blood offering, of beast or bird, or man, can take away sin, for how can the conscience be purged from sin by the shedding of innocent blood ? Nay, it will increase the condemnation.
The priests indeed receive such offering as reconciliation of the worshippers for the trespasses against the law of Moses, but for sins agains the Law of God there can be no remission, save by repentance and amendment.
how do we understand sacrifice?
CHRIST CHOSE TO BECOME THE ULTIMATE SACRIFICE
1 Samuel 15:22 And Samuel said, Hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
Sacrifice is leaven from the pharisees:
Matthew 16:12 Then understood they how that he bade them not beware of the leaven of bread, but of the doctrine of the Pharisees and of the Sadducees.
Ezekiel 5:6 And she hath changed my judgments into wickedness more than the nations, and my statutes more than the countries that are round about her: for they have refused my judgments and my statutes, they have not walked in them.
-Corruption of the covenant of Levi:
Malachi 2:8 But ye are departed out of the way; ye have caused many to stumble at the law; ye have corrupted the covenant of Levi, saith the LORD of hosts.
-Blood Sacrifice is not what our Father in Heaven wants:
Psalms 51:16 For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering.
17 The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.
Isaiah 1:11 To what purpose is the multitude of your sacrifices unto me? saith the Lord: I am full of the burnt offerings of rams, and the fat of fed beasts; and I delight not in the blood of bullocks, or of lambs, or of he goats.
-Blood Sacrifice was not commanded by our Father:
Jeremiah 7:22 For I spake not unto your fathers, nor commanded them in the day that I brought them out of the land of Egypt, concerning burnt offerings or sacrifices:
-Blood sacrifice is "of fools" and evil:
Ecclesiastes 5:1 Keep thy foot when thou goest to the house of God, and be more ready to hear, than to give the sacrifice of fools: for they consider not that they do evil.
