Colossians 2:13-23 (KJV)
13 And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses;
14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
17 Which are a shadow of things to come; but the body is of Christ.
18 Let no man beguile you of your reward in a voluntary humility and worshipping of angels, intruding into those things which he hath not seen, vainly puffed up by his fleshly mind,
19 And not holding the Head, from which all the body by joints and bands having nourishment ministered, and knit together, increaseth with the increase of God.
20 Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances,
21 (Touch not; taste not; handle not;
22 Which all are to perish with the using;) after the commandments and doctrines of men?
23 Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body: not in any honour to the satisfying of the flesh.
What specifically is the "shadow of things to come" in v. 17 which is representative of and fulfilled in Christ? Does this refer to certain specific Old Testament laws that are no longer binding? If so, which ones? Or does this refer to extra-Biblical additions to the law invented by people like the Pharisees? If so, then what is referred to as the "handwriting of ordinances" against us in v. 14 (and possibly also v. 20)?
I agree that, in general, the principals of the Mosiac law are still part of God's revealed will for Christians to follow. However, my question specifically is, are there some aspects of the law mentioned here (such as the Mosaic laws related to meat, drink, holyday, new moon, or sabbath days) that are no longer binding?
