I knew a guy who was Oneness Pentecostal and a very strange, cold, type of guy. I went to the services and they were very dramatic and noisy, but there was no kind of the spiritual love, joy, and character (what I would describe as Spiritual E/c2) that I found from the Saints of old. This man ends up backslidding and living a wild life and his church fell apart. Talking to this guy after he backslid, he had a warmer spirit than he did while with the Oneness Pentecostals. He ended up moving to Florida and I have not seen him since.
It is important to measure the type of people in Pentecostal churches. Now, I am Pentecostal, and don't have any intentions of turning into anything else.... But... Not everyone who makes a noise in those churches are truly filled with the Holy Spirit. If it is something strange and cold to you leaving there was your best option.
I fell in with the Pentecostal Holiness church not because of the tongues, but because of the people, which were the finest I have ever met in my entire life. Pictured below is Dallas Linkous JR, which is probably the 'shoutingest' man I have ever met in my entire life. As a teenager I would put up hay with him and go with him to the revivals at night. Both him and his wife were tongue talking, shouting, happy type Pentecostals. The joy was there equally there at home as well as at work. Every one of the fruits of the spirit lamped within their lives like a great over heated pot belly stove. There was also a decency among the people like I have never seen. My grandfather was good friends with Dallas. In the 1950's they would have revivals that would go for weeks and early in the AM. Granny said that grandfather could worship the Lord until 2 AM and not have any trouble at all rising at 6 AM for work.
I remember well as a young man Dallas coming behind me to pray with me at the altar, with tears running down his cheek and onto my neck. As a guy who did not like to be touched this was quite profound. At the end of that summer we had a good revival in which the Lord seemed there in a mighty way. On reading the book, "Run Baby Run," by Nikki Cruise, I felt a voice telling me to put the book down. I paused, and then continued again to read. The voice said again, "Put the book down." I slept in my Grandmothers living room on an old fold away cot by the open living room door. The Katydids seemed to be singing very loud that night. There in my Grandmothers clean linens I heard the Spirit speak again, "Where is all the stress, worry and hatred?" In which, upon examining my heart, there was nothing there but pure beauty. I thought to myself. "Oh my! I got exactly what those people got!" I would spend the rest of the summer rejoicing with the people and in revival until I went back to college later that September.
I believe these people were actually filled with the Holy Spirit, not only for the noise, but for the goodness of character that followed the experience.
