§ 8. Now the duke, John George, after his virtual adoption of the Reformed faith and practice, issued a peremptory order that the formula of Exorcism should no longer be employed in his dominions at the baptism of any infant. Arndt, who was characterized by a childlike submission to those in authority, as long as matters of principle were not involved, could not renounce his faith in God’s word, and, especially, his personal conviction of the natural depravity of the human heart. He might have consented to drop a mere form; but he saw here an entering wedge, which justly alarmed him. His apprehensions were subsequently proved to have been only too well founded, when, soon afterwards, Luther’s Catechism was suppressed, and another substituted in its place. Hence, as he could not renounce a prominent feature of the Lutheran creed, he firmly and positively refused to obey the ducal command. He remarked, in the written statement which embodied his reasons for refusing to obey, and which was submitted to the civil authorities, that his conscience would not allow him to comply with such a demand of the secular authority—that the orthodox fathers, who had, during thirteen centuries, connected “exorcism” with Baptism, understood it in accordance with the mind and true sense of the Scriptures (_ex mente et vero sensu Scripturæ_)—that it was, therefore, by no means “an impious ceremony” (as the civil ruler, a layman, had thought proper to designate it),—that he must necessarily abide by the decision of his conscience—and, that he would humbly submit to any sentence which his prince might pronounce in the case. The date which he affixed to the document, is Sept. 10, 1590. That sentence, which was soon afterwards proclaimed, deposed Arndt from his office, and banished him from the ducal territories. The reader of Book I. of the “True Christianity,” will now understand, after observing the earnestness with which the author insists on the doctrine of Original Sin, or the depravity of human nature, that he could not conscientiously take any step which would, even indirectly, involve a denial of that sad truth of the Bible,—a truth to which his knowledge of his own heart daily testified.
