One reason there’s over a billion Catholics worldwide. And also the reason it’s lasted 2,000 years.
It’s the truth. Quick give me a long list of well-known Catholics that converted to protestantism. You can’t.
Now want me to give you an endless list of former protestants who converted to Catholicism. I didn’t think so.
Friend, truth is determined by the Word of God, never by how many embrace an idea or by how long an idea has been embraced.
And don’t forget, the Mystery of Iniquity was already at work in the days of the apostles, so that 2,000 year history you claim ought to give you great pause.
Would a VERY long list of NOT-WELL KNOWN ones works for you?
I can give you a list of well-known MORMONs in the entertainment industry give you a tingle?
