After the Diet of Augsburg Martin Luther had to appear at the Fuggerhäuser in 1518 before cardinal Thomas Cajetan to answer for his 95 theses. He arrived in the city on 7 October and left on 20 October - during his stay he lived in the same abbey as Langenmantel, who took care of him and gave him advice.

Christoph's father Georg was then serving as mayor and on the night of 19–20 October Christoph led Luther through a secret gate in the city wall to escape.
