I was brought up in the Church of God and they spoke in tongues. Their belief was that if someone spoke in tongues someone else in the church would interpret what the speaker said. My mother believed in it until the day she died.
All religions change over the years. As the public starts to make fun of people speaking in tongues churches stop doing it. The church I grew up in taught that women should not cut their hair. In the 80s they dropped the rule. I was never told that God sent them word that it was okay to go to the beauty shop.
And keep in mind the Mormons quit having plural marriages. However, they never said Joseph Smith was wrong so it’s still part of their “belief”.
I’m Church of God, although I came up in the 90s after they’d dropped the legalism. (Although occasionally I see some elder women who still refuse to wear make-up, short hair, jewelry, anything other than long skirts, etc., simply as a matter of personal preference).
Church has changed over the years, and while I don’t agree with any of those practices, I am holiness and will die holiness. I still go to my church because our pastor still preaches the blood of Jesus, speaking in tongues, living free from sin, and miracles and healings. I really no longer care about denomination; the moment that changes, I will be out the door to never return. Mankind may change over the years, but God doesn’t. We wonder why the power isn’t there anymore...
