81. Astoundingly, the teaching that faith is the only thing that justifies us occupies every square inch throughout the entire Protestant world; that is, within the clergy it rules as virtually the only theology. This position is what all candidates for the ministry eagerly learn, consume, and absorb in college. Then, as if they were people inspired with heavenly wisdom, they teach that position in their churches and publish it in their books. Through it they pursue and achieve the name, reputation, and glory of having superior erudition. Because of it they are given diplomas, fellowships, and awards. And all this goes on, despite the fact that as a result of that teaching alone the sun today is darkened, the moon is deprived of its light, and the stars of the heavens have fallen, that is, have been destroyed.

I have been given absolute proof that the teaching that faith assigns us justice has so blinded human minds today that they do not want, and are therefore virtually unable, to see any divine truth in the light of the sun or in the light of the moon. They can see it only in the light of a fireplace by night. I can therefore make this assertion: If divine truths about the true partnership between goodwill and faith, about heaven, about the Lord, and about the eternal happiness that comes from him were to be written in silver letters and sent down from heaven, people who believe that we are justified by faith alone would not even consider them worth reading. The complete opposite would happen, though, if a paper asserting that faith alone makes us just were to be sent up from below.

We also read in the Formula of Concord that the article concerning justification by faith alone, or concerning the justice that we acquire through faith, is the most important of all Christian teachings, and that works of the law must be completely excluded from this article (pages 17, 61, 62, 72, 89, 683; appendix, page 164).

18. Brief Analysis

The churches that separated from Roman Catholicism during the Reformation consist of those who call themselves Evangelicals and those who call themselves the Reformed and also Protestants, and who are named Lutherans or Calvinists after the founders of their churches. The Anglican Church holds middle ground between them. (I am not referring here to the Orthodox churches, which separated from Roman Catholicism a long time ago.)

Many people are aware that the Protestant churches have theological disagreements with each other in a number of areas — especially concerning the Holy Supper, baptism, the person of Christ, and the process whereby people become “the chosen.”

It is not widely recognized, however, that there are four points on which all these churches agree: there is a trinity of persons in the Divine; there is such a thing as original sin; Christ’s merit is assigned to us; and we are justified by faith alone. The reason this is not widely recognized is that few people conduct research on the dogmatic differences between the churches, and therefore few realize the points the churches have in common. Members of the clergy limit themselves to an investigation of the tenets of their own church; and lay people rarely examine those tenets deeply enough to see the differences and similarities.

Nevertheless, on these four points, Protestants do agree, both generally and in most of the details, as you will find if you consult their books and listen to their sermons. (This point is established first for the sake of the points that are about to follow.)
