The bolded is an outright lie, especially because you offered no biblical proof to back it up. Does God's grace allow people to commit idolatry, blasphemy, adultery, murder, and other sins with no consequence? No. Barney Bright did not misrepresent your argument because the bolded betrays the fact that you're selling lawless theology. Grace is not a license to disregard God's commandments or His laws, and Paul was emphatically clear about this:
"What shall we say then? Shall we continue in sin that grace may abound? Certainly not! How shall we who died to sin live any longer in it?" - Rom. 6:1-2
"Do we then make void the law through faith? Certainly not! On the contrary, we establish the law. - Rom. 3:31
"Circumcision is nothing and uncircumcision is nothing, but keeping the commandments of God is what matters." - 1 Cor. 7:19
Like other antinomians, you throw the baby out with the bathwater by assuming Christians don't have to abide by the moral principles required in the Law because Christ's sacrifice made the need for animal sacrifices obsolete, and that simply not the case at all. Everything that God said was sin under the former covenant is still sin under the current covenant. That hasn't been replaced or abolished by anything.
This a thousand times wrong, and the Bible shows why:
“But you shall not eat flesh with its life, that is, its blood." - Gen. 9:4
‘For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.’ “Therefore I said to the children of Israel, ‘No one among you shall eat blood, nor shall any stranger who dwells among you eat blood.’" - Lev. 17:11-12
Contrary to your claim, it has nothing to do with idol worship. Again, this is not a matter of someone misunderstanding your position but a matter of you selling bogus theology as biblical. The edict from Acts 15 concerns laws God already revealed in the OT, because everything the apostles taught and enforced can be traced directly back to the Law. Incidentally enough, it also disproves the widespread fallacy that the Acts 15 edict told people to disregard those laws.
