Ambrosiaster : We were therefore sons of the slave woman when we were liable for our sins. But, having received the remission of sins from Christ, we have been made free. — EPISTLE TO THE Galatians 4.31 Augustine of Hippo : Let us, therefore, choose whether to call the righteous men of old the children of the bondwoman or of the free. Be it far from us to say, of the bondwoman; therefore if of the free, they pertain to the new testament in the Holy Spirit, whom, as making alive, the apostle opposes to the killing letter. For on what ground do they not belong to the grace of the new testament, from whose words and looks we convict and rebut such most frantic and ungrateful enemies of the same grace as these? — AGAINST TWO LETTERS OF PELAGIUS 3.12 John Chrysostom : He turns and discusses this on all sides, desiring to prove that what had taken place was no novelty, but had been before typified many ages ago.

If then we are not children of a bondwoman, nor of slaves, how do we submit ourselves to the servitude of the law? We are not, since Hagar is not our example, but of the Jews. For Sarah is our example. — Commentary on Galatians Tertullian : Nay, rather banish quite away from your "free" head all this slavery of ornamentation. — On the Apparel of Women Book II
