Christ is the fulfillment of the Law with all of its feasts, special days, offerings, and sacrifices!

Matthew 5:17
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.”

Romans 10:4
Christ is the end of the law so that there may be righteousness for everyone who believes.

Romans 7:1-6
Do you not know, brothers-for I am speaking to men who know the law-that the law has authority over a man only as long as he lives? For example, by law a married woman is bound to her husband as long as he is alive, but if her husband dies, she is released from the law of marriage. So then, if she marries another man while her husband is still alive, she is called an adulteress. But if her husband dies, she is released from that law and is not an adulteress, even though she marries another man. So, my brothers, you also died to the law through the body of Christ, that you might belong to another, to him who was raised from the dead, in order that we might bear fruit to God. For when we were controlled by the sinful nature, the sinful passions aroused by the law were at work in our bodies, so that we bore fruit for death. But now, by dying to what once bound us, we have been released from the law so that we serve in the new way of the Spirit, and not in the old way of the written code.  

Galatians 4:4-7
But when the time had fully come, God sent his Son, born of a woman, born under law, to redeem those under law, that we might receive the full rights of sons. Because you are sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, “Abba, Father.” So you are no longer a slave, but a son; and since you are a son, God has made you also an heir.

Colossians 2:13-15
When you were dead in your sins and in the uncircumcision of your sinful nature, God made you alive with Christ. He forgave us all our sins, having canceled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross. And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.  

Hebrews 8:6
But the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, and it is founded on better promises.

Hebrews 10:5-10
Therefore, when Christ came into the world, he said:
“Sacrifice and offering you did not desire, but a body you prepared for me;
with burnt offerings and sin offerings you were not pleased.
Then I said, ‘Here I am-it is written about me in the scroll-
I have come to do your will, O God.’”
First he said,
“Sacrifices and offerings, burnt offerings and sin offerings you did not desire, nor were you pleased with them”
(although the law required them to be made).
Then he said,
“Here I am, I have come to do your will.”
He sets aside the first to establish the second. And by that will, we have been made holy through the sacrifice of the body of Jesus Christ once for all.
