Who is “us?”
Our refusal to go beyond what is revealed in these two Scriptural truths is not "masked Calvinism" ("Crypto- Calvinism") but precisely the Scriptural teaching of the Lutheran Church as it is presented in detail in the Formula of Concord (Triglot, p. 1081, paragraphs 57-59, 60b, 62, 63; M. p. 716f.): "That one is hardened, blinded, given over to a reprobate mind, while another, who is indeed in the same guilt, is converted again, etc. -- in these and similar questions Paul fixes a certain limit to us how far we should go, namely, that in the one part we should recognize God's judgment. For they are well-deserved penalties of sins when God so punished a land or nation for despising His Word that the punishment extends also to their posterity, as is to be seen in the Jews. And thereby God in some lands and persons exhibits His severity to those that are His in order to indicate what we all would have well deserved and would be worthy and worth, since we act wickedly in opposition to God's Word and often grieve the Holy Ghost sorely; in order that we may live in the fear of God and acknowledge and praise God's goodness, to the exclusion of, and contrary to, our merit in and with us, to whom He gives His Word and with whom He leaves it and whom He does not harden and reject...And this His righteous, well-deserved judgment He displays in some countries, nations and persons in order that, when we are placed alongside of them and compared with them (quam simillimi illis deprehensi, i.e., and found to be most similar to them), we may learn the more diligently to recognize and praise God's pure, unmerited grace in the vessels of mercy...When we proceed thus far in this article, we remain on the right way, as it is written, Hos. 13:9: `O Israel, thou hast destroyed thyself; but in Me is thy help.' However, as regards these things in this disputation which would soar too high and beyond these limits, we should with Paul place the finger upon our lips and remember and say, Rom. 9:20: `O man, who art thou that repliest against God?'" The Formula of Concord describes the mystery which confronts us here not as a mystery in man's heart (a "psychological" mystery), but teaches that, when we try to understand why "one is hardened, blinded, given over to a reprobate mind, while another, who is indeed in the same guilt, is converted again," we enter the domain of the unsearchable judgments of God and ways past finding out, which are not revealed to us in His Word, but which we shall know in eternal life. 1 Cor. 13:12.
