Try listening. Or reading. Every day, at every Mass, the Gospel is a central part of the service. If you are claiming the right to judge, shouldn’t you honestly listen to what the man you are judging actually says? And writes? Or is that too much work?
So, what is the Gospel, according to the RCC? Is it a verse of Scripture I can go to? Just what is the gospel of your salvation? If the Pope preaches it every day, what is it?
Some people prefer prejudice to education.
