Rev. Andrew's good friend Rev. Charles Lehmann, Lutheran pastor and classmate at Institute of Lutheran Theology, comes on the show for the first time to discuss the Communicatio Idiomatum; how Jesus’s human nature and divine nature are related which has been understood differently between the Lutheran and the Reformed traditions. We had a lot of fun. Charles will frequently appear on Doth Protest Too Much (so get used to him! :) )  *The debate between Jakob Andrae and Theodore Beza that is referred to in this episode is Colloquy of Montbéliard.    *The reference to Jesus's "divine spittle" from Athanasius of Alexandria is from his Discourse against the Arians. *The episode title is Charles's paraphrase of Martin Chemnitz's teaching from his work The Two Natures of Christ, p. 449.
