10. Teachings from the Formula of Concord on original sin:

(a) Since the fall of Adam, all human beings who are propagated according to nature are born with sin, which condemns and brings eternal death to those who are not born anew. The merit of Christ is the sole means and instrument through which we are reborn, and therefore the only remedy by which we are healed (pages 9, 10, 52, 53, 55, 317, 641, 644, and the appendix, pages 138, 139).

(b) Original sin is a corruption of our nature at such a deep level that there is nothing spiritually sound left in the human body or soul or in their powers (page 574).

(c) It is the source of all other, actual sins (pages 317, 577, 639, 640, 942; appendix, page 139).

(d) It is the complete absence or lack of the image of God (page 640).

(e) A distinction must be maintained between our nature, as it was created by God, and the original sin that resides within our nature (page 645).

(f) The volume refers to original sin as the Devil’s work, spiritual poison, and the root of all evils, and says it is an “accident” and a “quality.” Our nature, on the other hand, is there referred to as the work and the creation of God; it is our person, substance, and essence. The volume gives as a comparison the distinction between the person who is infected with a disease and the disease itself.

109. The notion that Christ’s righteousness or merit is assigned to us permeates the entire theological system in today’s Protestant Christian world. It is because of this assigning that our faith (which Protestant Christianity takes to be the sole means of being saved) can be referred to as our righteousness before God; see §11 d. The assigning that happens as a result of our faith clothes us with the gifts of righteousness, much as a newly crowned monarch is adorned with royal insignia.

In reality, however, this assigning accomplishes nothing if all it involves is that we are called righteous. It does no work within us; it only flows into our ears, unless this assigning of righteousness includes an actual transfer of righteousness to us through some process of its being shared with us and incorporated into us. This conclusion follows from the list of things that are claimed to be the effects of this assigning: our sins are forgiven, and we are regenerated, renewed, sanctified, and therefore saved. This claim is clearer still from the fact that Christ is said to dwell in us and the Holy Spirit is said to work in us as a result of that faith; and therefore we are not only considered to be righteous but actually are righteous. It is not just the gifts of God that reside in the reborn, but because of their faith, Christ too and in fact the entire holy Trinity dwells in them as his temple; see §15 l. Both we as people and the works we do should be called, and should be, completely righteous; see §14 e.

From these points it undoubtedly follows that “the assigning of Christ’s righteousness” must mean an actual transfer of righteousness to us through some process of its being incorporated into us, through which we become a partaker in it.

Now, because this concept of assigning is the root, the start, and the foundation of faith and of all the work faith does for our salvation, and because it is therefore the sanctuary and shrine at the center of all Christian church buildings today, it is important to add as an appendix [to this work] an examination of this notion of assigning, presented point by point as follows.

1. After we die we are all assigned either blame for the evil or else credit for the goodness to which we have devoted ourselves.

2. It is impossible to incorporate one person’s goodness into another person.

3. Given that this is impossible, it is an imaginary faith to believe that Christ’s righteousness or merit is assigned to or transferred into us.
