Many Calvinists like to try and pin the pre-destination label on Lutherans. I think maybe the Calvinists are just a little lonely in their corner of Christianity 😉 and are looking for someone else to huddle with.  

In tune with the last post here is another blog post by the CyberBrethren blogger on that topic. http://cyberbrethren.com/2009/12/16/refuting-calvinist-claims-that-luther-taught-double-predestination/ It does a pretty good job of refuting the claim that Luther believed in pre-destination. The post is pretty long, at least by my standards, but is worth the read if you are interested in this topic. I especially like the t-shirt shown.
