That's why there is a Catechism of the Catholic Church. People teach all sorts of things claiming it to be Catholic doctrine. But if it disagrees with the Catechism, it is incorrect.
The point I was making was that there are people here who present a false view of Catholic doctrine and even after being corrected and shown our actual beliefs, per the Catechism, they are back here the next day repeating their old canards like they never saw what the Catechism actually says. What's their purpose for doing this?
