Okay, the guy finally made his point at 9:00-10:48. His point is that, because exorcisms have failed and people have died and priests have suffered demon attacks, that the Church must be doing something wrong because those things aren’t shown in the Gospel.
First of all, it’s a logical fallacy. A failed exorcism doesn’t mean the Church is unbiblical, unless someone is claiming that God said, “failed exorcisms mean you did it wrong”.
This ties into the other blunder the guy made. Failed exorcisms ARE in the Gospel. You need look no further than Mt 17:19 where the disciples were unable to expel the demon.
His argument is refuted right there. But we can go on. Not only can a legitimate exorcism fail, but Christ goes on to tell us that some demons can only be expelled by fasting and prayer (in that same example). He goes even further to say that such required FAITH on the part of the patient (cf. Mk 9:18). Acts 19:13 shows us yet another failed attempt at exorcism by the Jews. Arguably this is because they had no authority to do such, but, as we see with the disciples who were sent out by Christ Himself, they were not always successful either.
There you go. A Biblical refutation of his “Biblical critique” against Catholic exorcism.
