I wonder if any of these gentlemen actually pray for an increase of the Gifts of the Holy Ghost, you know, the old ones like Wisdom, Knowledge, Understanding, Prudence, Fear, Piety and/or Fortitude? The fact that they don't pray for them, and wait to receive their plenitude by degrees, but instead, fancy themselves to call down at will gratis datae, and very poor imitiation at that, speaks volumes about their true spiritual state and understanding of the spiritual life in general. Extraordinary grace is by definition sinful to desire. Thus their "spirit filled" meetings are nothing but sin upon sin.
Mentioning allegedly "good" things that are derived from this aberration is kind of like being a used car salesman. They mention an apparent good, but fail to confront any problems. Take for instance the priest who decided not to leave the priesthood because of an "experience." So he didn't leave the priesthood, but what is the actual quality of the priest? Does he stay only to further destroy the Church? No one says because there is no real discernment. These men do not take a second look at anything in their intense desire to justify themselves. They are too infatuated with satisfying their own wills while pretending to call it an inspiration of the Holy Ghost. They haven't even begun to travel the way of the Spirit, a way that would utterly dismay and confuse them. But as was said, since they desire the extraordinary, the first sin of the spiritual life, they hand themselves over to the Devil in yet another of the myraid of ways in which he ensares souls.
