The Dr. Laura Letter

I came across the "Dr. Laura Letter" on the Internet.  I won't reproduce the letter here, but you can access it at www.snopes.com/politics/religion/drlaura.asp.  The letter sounds like it was written by a wise guy, but I'll give it a wise man answer.  A lot of pro-gay apologists try to get around the Bible's clear condemnation of homosexuality by diverting our attention to other subjects, usually Mosaic laws.  They argue that since Christians don't follow all the Levitical rules, they don't have to follow the Bible's moral and ethical laws either.  Now I can't speak for modern Judaism, though here's someone who can, but I can speak for why Christians don't have to follow the Mosaic rules.  The Lord Jesus Christ instituted a new covenant or testament that fulfilled and superseded the old covenant (Heb 8:7-13, quoting Jer. 31:31-34).  We'll look at specific issues.  I won't deal with them in order, however because I've already researched some areas more than others.
