And it is as much agreeable to an established course and order of nature, that since Adam, the head of mankind, the root of that great tree with many branches springing from it, was deprived of original righteousness, the branches should come forth without it. . . . Grace is introduced among the race of man by a new establishment; not on the ground of God’s original establishment, as the head of the natural world, and author of the first creation; but by a constitution of a vastly higher kind; wherein Christ is made the root of the tree, whose branches are his spiritual seed, and he is the head of the new creation.

— Jonathan Edwards,
The Great Christian Doctrine of Original Sin Defended
