The Augsburg Confession
Chief Articles of Faith
Article II Original Sin
[1] Our churches teach that since the fall of Adam [Romans 5:12], all who are naturally born are born with sin [Psalm 51:5], that is, without the fear of God, without trust in God, and with the inclination to sin, called concupiscence. [2] Concupiscence is a disease and original vice that is truly sin. It damns and brings eternal death on those who are not born anew through Baptism and the Holy Spirit [John 3:5].
[3] Our churches condemn the Pelagians and others who deny that original depravity is sin, thus obscuring the glory of Christ’s merit and benefits. Pelagians argue that a person can be justified before God by his own strength and reason.
