ACC ~ Galatians 4 v7
IF SON, THEN HEIR. AMBROSIASTER: There is no doubt that one adopts a son in order to leave him an heir; but inheritance depends on the death of someone. How then can mortals be called the heirs of him who lives forever? The fact is that Scripture speaks in our own manner so that we may understand. In order to show that the Father will give from his goods those things that he is going to give his sons, it calls this “inheritance.” PISTLE TO THE GALATIANS 4.7.
ONE IN CHRIST. JEROME: What we say in this place we should also observe in others, that the whole human race is being treated under a single term. For all we who believe are one in Christ Jesus and members of his body. EPISTLE TO THE GALATIANS 2.4.7.
