ISB ~ Romans 4 v17

I have made you:A citation from Gen 17:5.

• The passage shows that God had already made Abraham the father of nations before he gave him the covenant of circumcision (Gen 17:9-14). In Paul’s mind, this took place back in Gen 15:5-6, when the patriarch first believed that God would make him a father. It follows that circumcision, which came after his fatherhood was established by faith, cannot be the sign of Abrahamic sonship.

calls into existence:Reflects the belief that God created all things out of nothing (2 Mac 7:28) (CCC 296).
