Well, I don’t think it’s so much “bashing” the catholic charismatic renewal, as it is a concern that those in this movement often seem to think their movement has a monopoly on charisms or have rediscovered them or have rediscovered the Holy Spirit.
They do not seem to understand that the church has always had charisms of all kinds but what they consider charisms today are something usually seen only in movements like the pentecostals and the kinds of things they are doing have not been common throughout most of church history even among canonized saints.
It is a very emotional movement and often seems like some are trying to create an elite church within the church kind of thing.
There are many problems involved with this ‘movement’ including the deceptive ‘history’ of it that they try to present.
They are also many many dangers involved in this speaking in ‘tongues’ as you have no guarantee that what you are saying is of the Holy Spirit. If not mature and well-grounded in the faith you could easily be deceived.
Here is an interesting blog site of a woman who was very involved in the charismatic movement for decades and she explains many of the problems. Sometimes it helps to look at both sides of issues. Even if you disagree with her you might find it helpful to see what she has to say.
