A drunkard? The evidence is the opposite:
1)He was extremely productive, preaching several times a week—while teaching at the University. He also wrote prodigiously, multiple books, many letters, sermons, etc. Luther’s total written works amount to about 6 feet of shelves in a library. Translated the Bible from Hebrew and Greek into a common German (a language he pioneered). His New Testament translation astoundingly took something like 10 weeks. One thing alcoholics almost always have in common: Very low productivity.
2) Luther preached against drunkenness, saying it was inhuman & ungodly.
3) Records of his drinking were no more than average for late medieval Germans—where the water was bad, and beer was drank at every meal.
4) Pope Julius (with multiple mistresses and armies along with massive corruption) famously called Luther a “drunken German monk” which is why Romanists to this day accuse him of it.
As to the other quotes, there were a lot of “Fake News” and spurious quotes, even in the 16th C., spread by Romanists who hated Luther. Luther also had quite a sense of humour, and was often very bombastic, and used complex arguments—so without context these quotes are meaningless.
Luther pioneered the German language?
Maybe because he was tossing out books not to his liking.
