Calmeyer, as we shall see elsewhere, was quite familiar with scripture and wanted to be a Godly man, pleasing to God. We do not know for sure his specifically Christian depth, many of his frequent mentions of God come from the Old Testament and respectful reference to the Deity. For example, he quoted Ezekiel regularly, especially in his later years when he appears to have studied the Bible for consolation and solace in his depressed times when he despaired of the failure of Germans and the world to listen to what he felt were the injustices and lessons of the Nazis. He would have been aware of the following verse, inasmuch as he also “made himself available” for the calling of righteous action in the midst of Nazi atrocities.

Whom shall I send, and who will go for us? Then said I, Here am I; send me. Isaiah 6:8.

Calmeyer was by all accounts a pleasant, humble, though intellectually compelling and highly educated man. He could be strong-willed and unpredictable in argumentation, but he was respected, as he wished to be.

My eager desire and hope being that I may never feel ashamed, but that now as ever I may do honour to Christ in my own person by fearless courage. Phil. 1:20.
