Christian identifying as jesus/god himself

[Rhema]

i think there are verses which in their holy book very much contradict the principles of christianity,

It's somewhat obvious to me that there are verses in the Hebrew Bible that very much contradicts Judaism itself.

The passage from Jeremiah 7:22 caused me to do a deep dive into the accounts of all animal sacrifices, and once translation issues are resolved, the Hebrew Bible repudiates every such instance, Abel, Noah, Abraham, even Moses. Jesus preached that the Father forgives sin, not that the Father is paid for sin by an animal sacrifice.

i spoke to an atheist which insisted that christians must follow the law of moses,

We can discuss this further if you wish, but Yes, this is true, even by Jesus' teaching (cf. Mat 23:1-3 below). The problem is that what is claimed to be the law of Moses isn't the initial law of Moses. Again, Jeremiah 8:8 proves that even back then the law was altered by the scribes into a lie - that nobody had the law of Moses, which is why God had to keep sending the prophets - to correct their beliefs, but the priests would not have it, even to the point of killing the Son.

Then spake Jesus to the multitude, and to his disciples, Saying, The scribes and the Pharisees sit in Moses' seat: All therefore whatsoever they bid you observe, that observe and do; but do not ye after their works: for they say, and do not.​

- Matthew 23:1-3 KJV

But Gentiles have no clue what "Moses' seat" is, or what it means.

...but its already dealt with...

Sorry, ... I missed this.

By "it" do you mean the law? And by "dealt with", do you mean "dispensed with"? Perhaps that's so with Pauline Christians, but I'm an Acts 2:38 "Xhristian," and a follower of the teachings of Jesus -

Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to FIX. 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 MAY COME INTO A NEW STATE OF BEING. 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.​

- Matthew 5:17-19
