The Infallible Teaching of the Church

"The minimalist approach is dangerous," says Pope Francis. "Even teachings that are not infallible with their teachings of the ordinary magisterium, we are bound to believe, obey and follow them as well just at a different level" If you or I reject an infallible teaching of the church, let's say the assumption of Mary, it could be in my heart of hearts where I say, I ain't buying that. Not believing it. That's grave matter. And if I knowingly and deliberately reject that, that is grave sin."
