Well, for one, he makes baseless assumptions about what the Chuch “allows” or doesn’t allow. Scripture is clear about the hierarchy and authority of the Church and the Pope, and Catholics are certainly allowed to read scripture to see this plain as day. He also asserts that Catholics are not allowed to read scripture in its original languages- also false.
I wouldn’t give this guy the time of day, personally. I’ve heard much more convincing Protestant arguments.
Was there something in particular he said that you would like a Catholic to address?
