Dates: c. 1533 (the Torgau sermon) · Wikipedia
Summary: Martin Luther (1483–1546), the Wittenberg reformer, gave the descent into hell a reading
distinct from both the medieval Catholic one he broke with and from Calvin's later
one. In a celebrated Easter sermon preached in the castle at Torgau in 1533, he taught a
real, victorious descent: the whole Christ — God and man — descended after his burial and
destroyed hell and the devil's power, delivering believers from it. But Luther refused to speculate about
the manner of it (when, how, in body or soul): he pressed Christians to "stick to the words" in simple
faith and leave the mechanics for the next world. This is the reading the Lutheran
Formula of Concord (1577) later made binding.
hell has been torn apart for us through Christ, and that the devil's kingdom and power have been destroyed, which is why Christ died, was buried, and descended, so that they should no longer harm us or subdue us
— Third Sermon for Easter Day, Torgau, 1533 (tr. Paul A. Rydecki from the Weimar edition, WA 37), godwithuslc.org. For Luther the descent is not a journey to a holding-cell of waiting patriarchs (the limbus patrum he had already rejected) but an act of conquest: Christ went down to hell to wreck it. The point of the article is its benefit — that hell and the devil can no longer hold the believer.
He descended into hell, in order that He might also deliver us out from there who should have lain captive therein
— Third Sermon for Easter Day, Torgau, 1533, godwithuslc.org. Luther reads the descent soteriologically: Christ entered death and the grave, and then hell, precisely "that He might bring His own out from there." The accent falls on the believer's rescue rather than on the deliverance of the Old-Testament saints that the medieval scheme had foregrounded.
Whoever wishes to keep from veering off the straight path, let him only stick to the words and imagine them for himself in a simple way, as best he can.
— Third Sermon for Easter Day, Torgau, 1533, godwithuslc.org. Luther deliberately leaves the disputed questions — whether the descent happened before or after death, in body or soul, as suffering or as triumph — unanswered, treating them as beyond what the article requires. It is this self-limiting "Christian simplicity" that the Formula of Concord singles out and adopts.
