The Augsburg Confession Article II

Article II: Of Original Sin.

Also they teach that since the fall of Adam all men begotten in the natural way are born with sin, that is, without the fear of God, without trust in God, and with concupiscence; and that this disease, or vice of origin, is truly sin, even now condemning and bringing eternal death upon those not born again through Baptism and the Holy Ghost.

They Condemn the Pelagians and others who deny that original depravity is sin, and who, to obscure the glory of Christ's merit and benefits, argue that man can be justified before God by his own strength and reason.
