I couldn't find the actual texts. But here's some information about the Gotha and Erfurt programs: http://www.i-u.ru/biblio/archive/novgorodcev_ob/06.aspx. Also, http://fw.mega.dp.ua/bse/Bse/STRU-YA/3017.htm, this is from a dictionary.
Thank you, this will also be useful. I'll go to the library to look for the texts. ;)
It's interesting why almost everyone who writes about the Franks and other barbarians are priests?
Well, probably also because they knew how to write... Almost the only ones who did. And as AlexeyPank already pointed out, they were also people of higher status, like Caesar, etc.
