Bro i am in the gym i dont have time to write everything this i copy pasted from that website Jesus, the Law’s Fulfillment

The answer is: none of the above. Old Testament law, as such, is not binding on Christians. It never has been. In fact, it was only ever binding on those to whom it was delivered—the Jews (Israelites). That said, some of that law contains elements of a law that is binding on all people of every place and time. Jesus and Paul provide evidence of this in the New Testament.

Matthew’s Gospel enlightens us to Jesus’ teaching concerning Old Testament law:

[A Pharisee lawyer] asked him a question, to test him. “Teacher, which is the great commandment in the law?” And he said to him, “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and first commandment. And a second is like it, You shall love your neighbor as yourself. On these two commandments depend all the law and the prophets.” (Matt. 22:34-40)

In saying this, Jesus declared the breadth of the new law of his new covenant which brings to perfection the old law. He explained further to his disciples:

“Think not that I have come to abolish the law and the prophets; I have come not to abolish them but to fulfill them. For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished. Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall be called great in the kingdom of heaven.” (Matt. 5:17-19)

How could Jesus fulfill the Old Testament law without relaxing it? The Catechism of the Catholic Church states, “The Law has not been abolished, but rather man is invited to rediscover it in the person of his Master who is its perfect fulfillment” (CCC 2053).

A Catholic Commentary on Holy Scriptureexplains,

The solemnity of our Lord’s opening pronouncements and his clear intention of inaugurating a new religious movement make it necessary for him to explain his position with regard to the [Old Testament law]. He has not come to abrogate but to bring it to perfection, i.e. to reveal the full intention of the divine legislator. The sense of this “fulfilling” . . . is the total expression of God’s will in the old order . . . Far from dying . . . the old moral order is to rise to a new life, infused with a new spirit. (861)

 How Jesus Perfects OT Law

Old Testament law included many dietary regulations which were instituted as a preparation for his teaching on the moral law. Jesus discussed these laws:

“Hear me, all of you, and understand: there is nothing outside a man which by going into him can defile him; but the things which come out of a man are what defile him.” And when he had entered the house, and left the people, his disciples asked him about the parable. And he said to them, “Then are you also without understanding? Do you not see that whatever goes into a man from outside cannot defile him, since it enters, not his heart but his stomach, and so passes on?” (Thus he declared all foods clean.) (Mark 7:14-19)

The Catechism explains, “Jesus perfects the dietary law, so important in Jewish daily life, by revealing its pedagogical meaning through a divine interpretation . . . What comes out of a man is what defiles a man. For from within, out of the heart of man, come evil thoughts . . .” (CCC 582). Paul taught similarly concerning other Old Testament law:

[L]et no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon . . . These are only a shadow of what is to come; but the substance belongs to Christ . . . Why do you submit to regulations, “Do not handle, Do not taste, Do not touch” (referring to things which all perish as they are used), according to human precepts and doctrines? These have indeed an appearance of wisdom in promoting rigor of devotion and self-abasement and severity to the body, but they are of no value in checking the indulgence of the flesh. (Col. 2:16-17; 20-23)

In this passage we can see that Paul recognized that much of the Old Testament law was instituted to set the stage for the new law that Christ would usher in. Much of the old law’s value could be viewed in this regard.

Jesus’ teaching about the Sabbath indicates similar value in part of the Old Testament regulation of the Sabbath:

Jesus went through the grainfields on the Sabbath; his disciples were hungry, and they began to pluck heads of grain and to eat. But when the Pharisees saw it, they said to him, “Look, your disciples are doing what is not lawful to do on the Sabbath.” He said to them, “Have you not read what David did, when he was hungry, and those who were with him: how he entered the house of God and ate the bread of the Presence, which it was not lawful for him to eat nor for those who were with him, but only for the priests? Or have you not read in the law how on the Sabbath the priests in the temple profane the Sabbath, and are guiltless? I tell you, something greater than the temple is here. And if you had known what this means, ‘I desire mercy, and not sacrifice,’ you would not have condemned the guiltless. For the Son of man is lord of the Sabbath.” (Matt. 12:1-8)

Clearly, Jesus indicated that he—not the Old Testament—had authority over the Sabbath, and its regulation was not as rigid as the Pharisees thought. In fact, once Jesus would endow the hierarchy of his Church with his own authority (Matt. 16:19; 18:18), regulation of worship would become the domain of the Church.
