The Devil Hates Latin or English

Father Vincent lambert is an exorcist. He says the devil hates latin because it's the official language of the church. If i'm not in a state of grace and i'm trying to do an exorcism, nothing good's going to come from that. You know, ex opere operato meaning when a priest celebrates the sacraments,. theyare always efficacious, even if the priest is unbelieving or sinful... But that's not the case in an exorcism.
