Frankly, I'm disturbed by the Catholic Pentecostals and their entire history of derivation from Protestant Holy-Rollers. There symptomatic behavior (speaking in "tongues", ecstasies, etc.), is a classical manifestation of demonic possession. When I observed them once at Mass at Steubenville, I found them to be a bunch of terrifying freaks - with their bizarre behavior during the minor elevation (everybody starts crying out in unintelligible tongues). It reminded me of the noise I heard on a tape of an exorcism being performed. If it is not the Evil One at work, self-suggestion seems to be the other method.
Any movement that begins in violation of some of the basic premises of Canon Law, such as Canon 1258 in the 1917 code, is certainly suspect.
Unsurprisingly this movement tends towards cultish behavior, as at the Mother of God community outside Washington, DC.

Good critical article demolishing this new Montanism here:

There has been a great deal of Protestantization creeping in from sources within modern American culture. Some Catholics seem to be getting confused and modelling their religious behavior on the pop customs of fringe Protestantism.
