Johannes Kepler's most important publication on questions of religion and confession, his Profession of Faith appeared in 1623 when the universal scholar Matthias Bernegger had an edition of one hundred copies printed in Strasbourg — at Kepler's expense — under the title: Glaubensbekandtnus vnd Ableinung allerhand desthalben entstandener vngütlichen Nachreden. With this booklet, Kepler intended to demonstrate that his religious convictions did indeed stand in harmony with the Bible; in addition, he strove to refute the accusations of heterodoxy brought against him, the “gossip” or “Nachreden” as he called it. His argument peaks in the next passage: “It is indeed quite an irksome matter, and one very much a matter of great agitation for the average, uninformed man, that someone could be so foolhardy, proud, and swollen-headed as to join no [religious] party. But I swear by God that I have not found joy in the situation nor found any peace therein. It causes me great grief that the three large factiones have torn the truth so terribly among themselves that I am forced to search and piece the truth together where I find it.”
