I agree completely Pilgrim that the author of the Wikipedia article put in his own interpretations however, I must also point out truly confessional Lutherans hold that Calvinist theology is a different gospel and as such they can't and will not join together with those of Calvinist beliefs.

Example 1: Differences between Calvinism and Lutheranism

Example 2: Taking the mask off of Calvinism

Example 3: Hour 3 Dr. Leonard Payton from Calvinism to Lutheranism

Example 4: Kim Riddlebarger: Tuesday, February 3rd, 2009

Now I haven't listen to the MP3s just haven't had time but if they are indicative of what I have heard from confessional Lutherans (ELCA don't count tongue) then they are definitely viewing Calvinism as screwing up the gospel.

Peter

If you believe what you like in the gospels, and reject what you don't like, it is not the gospel you believe, but yourself. Augustine of Hippo
