Rodney Howard Browne met with Todd Bentley early in the Lakeland meetings. ‘My advice to you is do not talk about angels, do not get off on angel Emma, preach the word of God and let’s see what God does.’ And Todd agreed with him. But the very next day in defiance, Todd said at the meeting: ’Someone recently told me that I’m not going to talk about angels’ – then he chanted in a demented and pagan way for the angels to come, then he also got the crowd to chant for angels in a demented and pagan way.

There is a video here of Todd invoking the angels http://www.youtube.com/watch?v=WA4aGlYW7HQ
