For a very thorough answer, from a Presbyterian perspective, read Charles Hodge, Systematic Theology, and look up Luther, and Lutheran Doctrine in the index. There you will find a well done treatment of each doctrinal difference, backed up with scriptural citations, and lots of reasoning to explain his interpretations. Hodge was a genius, pious, and respectful (especially of other's views).
It's important to remember that there are after all, very few differences between Lutherans and Presbyterians.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
