but what saith the scripture? "cast out the bond-woman and her son; for the son of the bond-woman shall not share the inheritance with the son of the free-woman."

he, who was of the bond-woman, was born according to the ordinary course of nature; but he, who was of the free-woman, was born by virtue of the promise.

so then, my brethren, we are not children of the bond-woman, but of the free-woman, by virtue of that freedom which Christ has procur'd for us.
