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.

76. Seven chapters in the Book of Revelation deal specifically with this affliction or attack by falsities against the truth. This attack is meant by the black horse and the pale horse that came forth from the scroll when the Lamb opened its seals (Revelation 6:5– 8). This attack is meant by the beast that rose up from the abyss and made war against the two witnesses and killed them (Revelation 11:7 and following). This attack is meant by the dragon that stood before the woman who was about to give birth, waiting to devour her child, and persecuted her in the desert; there it sent forth water like a river from its mouth to swallow her up (Revelation 12). This attack is also meant by the beast from the sea, who had a body like a leopard, feet like a bear, and a mouth like a lion (Revelation 13:2). This attack is also meant by the three spirits that were like frogs, which came out of the mouths of the dragon, the beast, and the false prophet (Revelation 16:13). Finally, this attack is what is meant by the fact that after the seven angels poured out their bowls full of the wrath of God, which were the seven last plagues, onto the ground, into the sea, into the rivers and springs, into the sun, onto the throne of the beast, into the Euphrates, and finally into the air, there was a great earthquake unlike any that had occurred since the creation of humankind on the earth (Revelation 16). The “earthquake” means that the church is turned upside down; this is brought about by people teaching what is false and falsifying the truth.

Similar things are meant by the following passage as well:

The angel put forth his sickle and harvested the vineyard of the earth, and threw it into the great winepress of the wrath of God. And the winepress was trampled, and blood came out, up to the horses’ bridles, for one thousand six hundred stadia. (Revelation 14:19, 20)

“Blood” here means truth that has been falsified.

There are many other examples in those seven chapters; see, if you wish, the explanations of those chapters and the accounts of memorable occurrences that come after them.
