Paul also contradicted the Law.
"But the righteousness which is of faith speaketh on this wise, Say not in thine heart, Who shall ascend into heaven? [that is, to bring Christ down from above] or, who shall descend into the deep? [that is, to bring up Christ again from the dead]. But what saith it? The word is nigh thee, even in thy mouth, and in thy heart: that is, the word of faith, which we preach....",
Rom. 10:6-8
Paul mutilated Deut. 30:12-14
"It is not in heaven, that thou shouldest say, Who shall go up for us to heaven, and bring it unto us, that we may hear it, and do it? Neither is it beyond the sea, that thou shouldest say, Who shall go over the sea for us, and bring it unto us, that we may hear it? But the word is very nigh unto thee in thy mouth, and in thy heart, that thou mayest do it".
The latter is only saying that his (Moses) commandments are easy to obtain. They are not far off but as close as one's heart or mouth. Deut. says nothing about "faith."
It refers to seeking "it" and doing "it," not seeking "him" or doing "him."
It does not even imply Christ or Jesus, let alone mention him.
Deut. is referring to Penitence and is not about believing on or bringing down Jesus from heaven or up from the dead.
Deut. is saying that God wills us to repent of sin and that you may know when you have sinned. You have only to look at his law which is very close by.
