Here is an excerpt:
THAT the doctrine of original sin is one of the fundamental truths of our Christian profession hath been always owned in the church of God; and all especial part it is of that peculiar possession of truth which they enjoy whose religion towards God is built upon and resolved into divine revelation. As the world by its wisdom never knew God aright, so the wise men of it were always utterly ignorant of this inbred evil in themselves and others. With us the doctrine and conviction of it lie in the very foundation of all wherein we have to do with God, in reference unto our pleasing of him here, or obtaining the enjoyment of him hereafter, it is also known what influence it hath into the great truths concerning the person of Christ, his mediation, the fruits and effects of it, with all the benefits that we are made partakers of thereby. Without a supposition of it, not any of them can be truly known or savingly believed.
