So basically ihop and KCEF believe and do what the majority of charismatics already believe and do. They believe salvation is assured when a person accepts Christ as savior. They believe in baptism as a sacrament, not needed for salvation. They believe in the HG and speaking in tongues, but again, mostly as a cool gift which is added after salvation.
Beyond that, ihop and Mike Bickle promote eastern philosophy and catholic mysticism -- lectio divina and contemplative/centering prayer.
I would like to say I'm surprised, but I'm not really surprised that Mike would gladly join them even with these beliefs if they were only not trinitarian; yet he consistently blasts holiness, new birth apostolics who either don't have the same eschatology belief as him or are against beards.
