He criticized the church because now only exorcists can perform exorcisms while before even regular priests, he also quoted Jesus from the bible who said that God gave men the ability to cast out demons, not just priests. Again, it is about intent and faith. That transcends a piece of paper.
There was a funny story I read on Reddit about this grandma who was gifted and could easily see spirits and stuff. One day her daughter was scared cause there was a demon in their house (demons and spirits are naturally attracted to those who can sense them). She said as soon as grandma saw it, she screamed "get the fuck outta my house!" With absolute conviction and the demon poofed away like a scared cat.
