Hello Justbyfaith,
While i was looking for passages for a reply to your post No.5, i have found a passage that you cannot contradict or deny;
Matthew 5:17-20:
Jesus son of God said: Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
18For 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.
19Whosoever 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.
20For I say unto you, That except your righteousness shall exceed
the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.
Also, i found a very interesting article, I encourage you to read it through it is very informative and truthful.
