In response to an earlier essay, a learned reader directed me to Seridei Eish (2:53:7, 2:149 in old editions), where Rav Yechiel Ya’akov Weinberg permits sermons in the local language. He distinguishes between prior generations, in which sermons were given in German in order to draw people toward the German Enlightenment, and his generation in which German sermons are used to draw people to traditional Judaism. He even says that if the Chasam Sofer were alive at the time of the writing of the responsum, he would be very happy to see traditionalist rabbis preaching in German in order to fight foreign influences.
I am happy to see that his analysis corresponds to my suggestions.
