“But Abraham, (you say,) was circumcised. Yes, but he pleased God before his circumcision; nor yet did he observe the Sabbath. For he had "accepted" circumcision; but such as was to be for "a sign" of that time, not for a prerogative title to salvation. In fact, subsequent patriarchs were uncircumcised, like Melchizedek, who, uncircumcised, offered to Abraham himself, already circumcised, on his return from battle, bread and wine.”
“But how are we children of faith? and of whose faith, if not Abraham's? For since "Abraham believed God, and it was accounted to him for righteousness; " since, also, he deserved for that reason to be called "the father of many nations," whilst we, who are even more like him in believing in God, are thereby justified as Abraham was, and thereby also obtain life-since the just lives by his faith,-it therefore happens that, as he in the previous passage called us "sons of Abraham," since he is in faith our (common) father, so here also he named us "children of faith," for it was owing to his faith that it was promised that Abraham should be the father of (many) nations.”
“For, albeit comeliness is not to be censured, as being a bodily happiness, as being an additional outlay of the divine plastic art, as being a kind of goodly garment of the soul; yet it is to be feared, just on account of the injuriousness and violence of suitors: which (injuriousness and violence) even the father of the faith, Abraham, greatly feared in regard of his own wife's grace; and Isaac, by falsely representing Rebecca as his sister, purchased safety by insult!”
“For albeit it is subsequently that he is called "a father of many nations," still it is of those (nations) who, as the fruit of the "faith" which precedes digamy, had to be accounted "sons of Abraham."”
