It never ceases to amaze me how people don't read the bible. If one doesn't understand that the 10 commandments are done away they can not understand what Christ came to do.
Luk 16:16 The law and the prophets were until John: since that time the kingdom of God is preached, and every man presseth into it.
The term "Christ" represents "the King of the Jews":
"Where is he that is born "King of the Jews"? for we have seen his star in the east, and are come to worship him. When Herod the king had heard these things, he was troubled, and all Jerusalem with him. And when he had gathered all the chief priests and scribes of the people together, he demanded of them where "Christ" should be born. And they said unto him, In Bethlehem of Judaea: for thus it is written by the prophet, And thou Bethlehem, in the land of Juda, art not the least among the princes of Juda: for out of thee shall come "a Governor, that shall rule my people Israel".
Notice how Herod uses the term Christ synonymously with the term King of the Jews and how the chief priest and scribes respond to Herod's question of where the Christ is to be born (In Bethlehem of Judaea: for thus it is written by the prophet, And thou Bethlehem, in the land of Juda, art not the least among the princes of Juda: for out of thee shall come "a Governor, that shall rule my people Israel"). It is clear that the term "Christ" was used to reference the anointed Heir to David's throne, the Messiah: the rightful heir to Rule God's people. If you are going to have a proper relationship with Jesus, you must relate to him as your Ruler: in obedience.
The 10 Commandments are absolutely done away as Jesus' Rule replaced the 10 Commandments.
The law is not a reference to the Torah, almost always the law is a reference to mankind's obligation to live right before God on any moral plain of existence. I know many of you that believe the Torah is still relevant are screaming inside yourself but let me ask you this question: why don't you stone adulterers to death as Moses commanded in the Torah?
For those of you that believe Paul's writings are inspired of God, why don't you believe Paul:
2Co 3:7 But if the ministration of death, written and engraven in stones (what was written and engraved in stones? THE 10 COMMANDMENTS), was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
2Co 3:8 How shall not the ministration of the spirit be rather glorious?
2Co 3:9 For if the ministration of condemnation be glory (This is a reference to the 10 Commandments being the ministration of condemnation), much more doth the ministration of righteousness exceed in glory.
2Co 3:10 For even that which was made glorious had no glory in this respect, by reason of the glory that excelleth.
2Co 3:11 For if that which is done away was glorious (Paul clearly is saying the 10 commandments are DONE AWAY), much more that which remaineth is glorious.
This isn't the only place Paul addresses this
Gal 4:21 Tell me, ye that desire to be under the law, do ye not hear the law?
Gal 4:22 For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
Gal 4:23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
Gal 4:24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar. (Paul says the first Covenant leads to bondage)
Gal 4:25 For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.
Gal 4:26 But Jerusalem which is above is free, which is the mother of us all.
Gal 4:27 For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.
Gal 4:28 Now we, brethren, as Isaac was, are the children of promise.
Gal 4:29 But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.
Gal 4:30 Nevertheless what saith the scripture? Cast out the bondwoman (The Law) and her son (And those who follow it): for the son of the bondwoman (those who follow the law) shall not be heir with the son of the freewoman (those who follow Christ).
Gal 4:31 So then, brethren, we are not children of the bondwoman (those who follow the law), but of the free.
Matthew 5:17 is very poorly written in English. Jesus was saying that he came to raise the standards of the law, not to lower them, but he didn't preach the Torah. If you think salvation is in the 10 commandments you have totally missed Jesus message: Jesus raised the standards of the law and replaced its teachings with a higher set of rules.
