The Authority of Mary's Sinlessness

The belief that Mary was without sin is officially taught by the Church, framing her as sinless both before and after her earthly life. Although this teaching is widely accepted, it has not been infallibly defined, meaning that there remains a theological debate regarding its absolute necessity for Catholic belief. The discussion revolves around whether the teaching about Mary's sinlessness demands the same level of assent as infallibly defined doctrines. The Church holds that while the teaching reflects high authority, it allows for exceptional dissent under specific circumstances if robust reasons are posed.
