To Florus 2.158

Earlier, then, he had worked to make us understand that the Gentiles could not be excluded from the fellowship of righteousness, but through the same faith are counted in Abraham’s family with the children of circumcision. Now he has added that none of the circumcised belongs to the promise given to Abraham. Unless properly understood, this is a complete contradiction. Therefore, when he says, ‘For if those who are of the law are heirs, faith is emptied and the promise destroyed’ (Romans 4:14), he did not declare that no Jew can be believed to become an heir of the ancient promise through faith. Rather, a word is missing, whose place understanding supplies: those of the law are not the only heirs. It is as though he had said, ‘For if those who are of the law alone are heirs, faith is emptied.’ The uncircumcised would indeed seem excluded if the inheritance of blessing reached none beyond the circumcised. We must therefore understand scriptural usage: what is not said is not automatically denied. Understanding must supply what the words leave out.
