Sigmund Freud (Austrian neurologist and psychologist) was an Austrian neurologist and psychologist. He left Austria in 1938 to escape Nazi persecution and died in the United Kingdom the next year.
Keep in mind that many of Freud's ideas go opposite to what the Bible says. One can see this just by reading some of his quotes.
When pastors attempt to use modern psychology, based on Freud's ideas, in sermons, it is like a "
bait and switch" where terms are defined and, instead of using Bible support, modern psychology ideas are substituted.
