Quanta Cura & The Syllabus of Errors
Quanta Cura & The Syllabus of Errors is an encyclical letter issued by Pope Pius IX in 1864. It includes a list of eighty propositions that the Pope condemned as erroneous, addressing what he viewed as the dangers of Modernism within the Catholic Church. This document served to guide bishops in identifying and rejecting these 'pernicious doctrines,' and it has influenced subsequent papal teachings against Modernism.
