There was a CNN show regarding faith healings, etc and one of the people interviewed was a charismatic Catholic priest through whom healings were happening. He said one thing that I appreciate to this day. He said "Receiving the holy spirit (with speaking in tongues) is like being on a honeymoon with the Lord"
I also found one thing somewhat humorous. He would pray the Catholic stuff "name of father, son, holy ghost," and whatever else...THEN when he was really getting down to business he would use the name of JESUS. (because there is salvation in no other).
