Some have observed and question why there are not too many apologists that come from a Lutheran background. Whereas there are many professional RC apologists, Reformed and non-Denominational ones, yet there are very few that stand out from the Lutheran camp. So far the most well known ones are Prof. John Warwick Montgomery and Prof. Rod Rossenblad. Even my finding KFUO was an accident (providential). So not too many.
They are obscure and when you do see them engaging in apologia, you do not see them debating topics like the existence of God, the Bible etc.
There are several reasons for this obscurity, and I think it is due to their philosophy.
1. For them the Pastor is Theologian and apologetics is done in the context of the parish environment. All Christian work, like apologetics is done in the context of a pastoral sphere. This is a different concept when compared to idea of para-church organizations.
2. They got the Book of Concord, their confession, which is highly apologetic in character. So in a manner of speaking, they can throw to you "the book". It codifies there their defense for believing what they believe.
3. They won't discuss with the atheist if God exists, or the issue of the Bible being the Word of God. No, they will discuss with the atheist Jesus Christ's resurrection from the dead. This is a different philosophy and it makes sense. One can convince an atheist to be a theist but that still misses the point, one can be convinced that the Bible is the Word of God but that still falls short. None of these makes one a Christian. So, they will discuss Jesus with the atheists as foolish from a logical standpoint that might seem.
The point is that Jesus Christ the Lord has come already and that has changed things. God proved he more than exists, he went further, he proved he loves us. The atheist does not need a God who hates him and who simply makes demands. He also needs to know that the God he does not want to believe in, actually loved him. Christ is proof of that. You hit many birds with that one stone. God, the Bible, life's meaning falls in place when the atheist sees the Christ...given for him.
