Some works named in the "Index Librorum Prohibitorum" are the writings of Desiderius Erasmus, a Catholic scholar who argued that the Comma Johanneum was probably forged and "De revolutionibus orbium coelestium", a treatise by Nicolaus Copernicus arguing for a heliocentric orbit of the earth, both works that at the time contradicted the Church's official stance on particular issues.
