Oh Pleeeeeeze! The very last thing this person needs is confusion coming from you or anyone else. For anyone willing to pay attention the Bible is very clear on what to do about spiritual attacks: (Mark 16:17) "These signs shall follow those who believe in me, In MY NAME they shall cast out demons......"
It is the authority placed upon believers in the name which is above other names that has power over dark entities, not a particular person or denomination, much less an idolatrous organization which bases its ministry on human rites and rituals. There are numerous ministries all over the country that dedicate themselves to freeing bound up people. They are successful because they are filled with the Holy Spirit, simply believe and put to practice simple Biblical instructions, without hockus pockus or dramatic fanfare.
