"You Lutherans have little in common with Luther theologically"

Every so often, folks from other camps especially the Reformed camp claim Lutherans are hardly in line with Luther theologically.

So let's put that to the test.

Confessional Lutheranism holds to Book of Concord as biblical rule of faith. That book contains three writings by Luther in full, three writings in full in Luther's lifetime that he agreed to and with, and a longer version of Formula of Concord that largely quote or paraphrase Luther (yes including his Bondage which was made binding on the Lutheran faith in it).

So explain again how we- confessional Lutherans- are out of step with Luther theologically again?

Here we stand.
