Deuteronomy 4:2 Ye shall not add unto the word which I command you, neither shall ye diminish ought from it, that ye may keep the commandments of the LORD your God which I command you.
1 John 3:4 Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
1 Peter 2:21-22 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps: (22) Who did no sin, neither was guile found in his mouth.
Matthew 5:17-19 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. (18) For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled. (19) Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
1) The Law of Moses says that no one may change the Law.
2) John said that anyone who violates the Law has sinned.
3) Peter said that Jesus never sinned.
4) Jesus said that he didn’t come to remove even a single ink mark from the Law and that anyone who does will be called the least in heaven.
5) If Jesus came to change the Law in even the smallest way, then he is a liar and a sinner, and he cannot be the Messiah.
I have never heard anything resembling a convincing counter argument. If you’ve got one, I’d love to hear it.
