"The Commentariolus’s early findings raised questions and exposed problems with the data. To avoid errors in his calculations and assumptions, Copernicus spent decades of his life finding the strongest evidence to support his epoch- shaking idea. The Commentariolus was only circulated among a few scholars and caused very little commotion.
In the meantime, Copernicus was busy with his duties with the church, whose very foundations were shaken by Martin Luther’s dramatic challenge to papal authority in 1517. Throughout the 1520s he helped steer his diocese through the ensuing conflict, taking part in diplomatic missions and even proposing reforms to the monetary system."
