Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
All Commentaries on Matthew 5:19 Go To Matthew 5
Cyril of Alexandria
AD 444
Whoever sets aside “one of the least of the commandments” of the law is set aside by God as God’s enemy and as an inventor of laws opposed to God. And now out of the law of the gospel that one receives the retribution which, under the ancient law, was not defined. For this reason Christ fittingly says, “I am not come to destroy but to fulfill.” For that which then was lacking, here is made full. It is said in the law: “Stand in the presence of the elderly” and “If you see the beast of your enemy fallen under its load, go help him lift it up.” If anyone transgressed these commandments, there was no retribution specified under the law. So Christ makes up this lack when he says that in the kingdom of heaven such a person will be treated with scorn.
