Micron wrote several books. In 1554, he published De christlicke ordinancien der Nederlantscher ghemeynten Christi, in which he promoted expository preaching: "the Scriptures are not expounded in sermons on isolated pericopes, as in the practice among the papists. Instead, we take some book of the Bible, either from the Old or the New Testament, and we expound it from the beginning to the end."[3] A Dutch catechism followed in 1555.
Micron had an intensive debate with Menno Simons regarding the incarnation.[4] Menno viewed Christ as possessing a celestial flesh,[5] while Micron believed that Christ took on human flesh and blood from Mary.[6] Menno likened Micron to the locusts of Apollyon.[6][7]
