Romans 4:10-12

Revised Standard Version Catholic Edition

¹⁰ How then was it reckoned to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised. ¹¹ He received circumcision as a sign or seal of the righteousness which he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised and who thus have righteousness reckoned to them, ¹² and likewise the father of the circumcised who are not merely circumcised but also follow the example of the faith which our father Abraham had before he was circumcised.
