Why would you ask that when I tell you Christians are under Jesus?
Examine yourself.
Tell me if Christians have to obey Jesus' teachings, teachings he taught while he walked the earth.
Explain why you would ask me if Christians are under the old law.
Ok, since you don't seem to be understanding what I'm asking, let me make it simple for you:
In Genesis 17, we see God giving to Abraham (not Moses, even though you correctly associate him with the Law) the Covenant of Law. This Covenant is one of faith AND works. You MUST keep the Law AND have faith in God to be saved.
In Genesis 15, two chapters earlier, we see God giving to Abram the Covenant of Grace. This Covenant is of FAITH ONLY. God put Abram into a deep sleep, and passed through the animals alone, to show that this covenant was unconditional, and Abram being asleep as God passed through signifies that we don't have to do anything for the covenant to be fulfilled, it's all on God.
So when I ask, "Are Christians under law or grace," I'm asking about the two Covenants given to Abram/Abraham, whom God calls the father of two groups of people.
All of Abraham's decendants are automatically under the Covenant of Law (Gen 17), whether they want to be or not, but for them to be saved, they had to BOTH obey the Law (which is to be circumcised, not the mosaic law, which is ceremonial and moral/civil laws, but which is under the circumcision).
In other words, "circumcision" and "law" are used synonymously throughout the Bible. Whenever you see anything pertaining to the "Law," it is (usually) talking about circumcision, and not the Mosaic law given by God on Mount Sinai.
But I'm not asking about Israel, who we know for a fact was under the law, for all of Israel was required to be circumcised.
I'm asking about Christians.
So to rephrase my question a bit differently, in the hope of getting a direct answer and maybe clarifying my point:
Should Christians be circumcised?
D) They're under the Law of Grace.
Most on TOL believe that.
Law + Grace = Genesis 17, what Israel was taught.
Grace alone = Genesis 15, what Paul preached.
