Sounds like it’s not authentic at all then.
This is the line I’ve read and heard from Charismatics, both Catholic and non-Catholic. What exhibits “wanting it” - muttering and babbling while swaying hands in the air? Is not feeling this is genuine “refusing it”? Seems a good way to slight anyone who questions the actions by saying they are not wanting and refusing this.
I have just changed my public profile to include “I have prayed quietly in Tongues for years.”
There could be all kinds of muttering and babbling and swaying hands in the air at some event billed as the perfect way of grabbing a gift from the Holy Spirit. If one attends such an event and is worried about the authenticity, my first suggestion is to check with the Pastor of the Catholic Church which sponsored this event.
Catholics have the responsibility to report violations of Catholicism to the Pastor and further up the ladder if necessary.
The Catholic Charismatic Renewal liaison is another person to contact. Years back, in my diocese, a warning was sent to all approved Charismatic groups. This warning was that a known preacher/teacher who provided false information about Catholicism and Renewal was headed toward our diocese. The liaison, being the link to the Bishop and his list of approved speakers, notified everyone. This liaison can also verify groups as being affiliated with the Diocesan Renewal or not.
Getting back to the point of "What exhibits “wanting it” – that is a personal decision. There are not 10 commandments for exhibiting. An interested person has to discern between suggestions and personal reality. However, I have heard that a Catholic Renewal preacher appeared to overstep his authority. A letter of concern was used.
Next, the liaison should be consulted for more appropriate preachers.
My personal opinion is that “wanting it” is connected to the decision of yielding to the Holy Spirit. Review post 52. My favorite suggestion is to try Tongues out loud in the shower.
If one does not want the gift of Prayer Tongues, no problem. Prayer is not a game where someone wins the prize for the “best.”
