I understand the qualms about the prosperity gospel milieu Ms. White apparently hails from ...but in the interactions I have observed and reflections she has shared with regard to the president and White House...I havent found anything she has said or prayed offensive.
Imperfect though we are, we are vessels of the Holy Spirit in a spiritual battlefield. The battle is not against flesh and blood, but the spiritual forces of darkness. Through Christ we are called to wage war against such forces and take authority in His name.
Her teachings are non-Christian. The prosperity gospel is antithetical to Christianity.
More so, for a pastoress to be on her third husband (and she being his fourth wife) is, well, not quite on...
