Gospel of Jesus Christ according to Saint Matthew (Mt 5, 17-19)

At that time, Jesus said to his disciples, “Do not think that I came to abolish the Law or the Prophets: I did not come to abolish, but to accomplish. Amen, I say to you: Before heaven and earth disappear, not a single iota, not a single trait will disappear from the Law
until everything comes true. So whoever rejects one of these smallest commandments, and teaches men to do so, will be declared the smallest in the kingdom of heaven. But whoever observes and teaches them will be declared great in the kingdom of heaven. “
