Perhaps, my point though was that some gospels advocate keeping the law, while others do not. Matthew advocates keeping the law.
That’s an interesting spin, but sort of irrelevant. Matthew’s Jesus was not advocating merely sliding by, which is what you would need to show.
Further, consider these verses:
5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
5:18 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.*
and obviously:
5:20 For 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.
Which puts a damper on your just do the minimum theory.
Jesus then goes on and gives a bunch more prescriptions. There is also this:
7:21 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven;* but he that doeth the will of my Father which is in heaven**. *
7:24 Therefore whosoever heareth these sayings of mine, and doeth them, I will liken him unto a wise man, which built his house upon a rock:
7:25 And the rain descended, and the floods came, and the winds blew, and beat upon that house; and it fell not: for it was founded upon a rock.
7:26 And every one that heareth these sayings of mine, and doeth them not, shall be likened unto a foolish man, which built his house upon the sand: *
*
19:17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
In other words, some people will profess to be Christians, yet they don’t do the will of the father and they will not enter into the Kingdom of heaven.
