To Florus 2.157

‘For if those who are of the law are heirs, faith is emptied and the promise destroyed’ (Romans 4:14). Unless this statement is understood, it introduces a very great difficulty. Undoubtedly by ‘those who are of the law’ he means those whom he had earlier called ‘of the circumcision.’ He knew they claimed so much for themselves that they thought no one besides themselves could be admitted to the dignity of Abraham’s offspring. Yet his argument had established that not only the circumcised, but also those of the uncircumcised who chose to follow the footsteps of Abraham’s faith, should rightly be reckoned Abraham’s children.
