Galatians 3:18-20

New Revised Standard Version Catholic Edition

¹⁸ For if the inheritance comes from the law, it no longer comes from the promise; but God granted it to Abraham through the promise.

The Purpose of the Law

¹⁹ Why then the law? It was added because of transgressions, until the offspring^[a] would come to whom the promise had been made; and it was ordained through angels by a mediator. ²⁰ Now a mediator involves more than one party; but God is one.
