If?? "The laws of ordinances were nailed to the cross", explain how that ended them, legally?
The cerimonial laws were added because of sin..
The cerimonial laws were established by God in the old testament to help people have faith in the coming Messiah.
They were all a type, shadow, schoolmaster of the real deal.
The lamb was a type of Christ the priesthood was a type of the ministry of Christ.
It is clear that God gave Moses a pattern of what is in heaven.
Exo 25:9 According to all that I shew thee, after the pattern of the tabernacle, and the pattern of all the instruments thereof, even so shall ye make it.
Heb 9:23 It was therefore necessary that the patterns of things in the heavens should be purified with these; but the heavenly things themselves with better sacrifices than these. 24 For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us:
The Earthly was a pattern of the real sanctuary in heaven. The Earthly are figures of the heavenly.
Heb 10:4-6 (also verse 1, and Heb 8:5)
4 For it is not possible that the blood of bulls and of goats should take away sins. 5 Wherefore when he cometh into the world, he saith, Sacrifice and offering thou wouldest not, but a body hast thou prepared me: 6 In burnt offerings and sacrifices for sin thou hast had no pleasure.
These figures did not do anything to save us. But in Christ and His ministry is full salvation.
These rituals were never intended to be permanent but were a temporary representation of the reality found in Christ.
Col 2:14-17
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.
Matt 27:51 "And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent." (This signified that the earthly sacrificial system was no longer of force).
Practicing the ceremonial law today is a denial of Jesus Christ’s finished work on the cross and a regression into a system of shadows that have already met their fulfillment in the true Substance.
The ceremonial law was a temporary system of types and shadows designed solely to point toward the coming of the Saviour.
Hope that helps.
