Today I visited a Charismatic church. They liked speaking strange tongues together, and prayed for the needy in strange tongues loudly. No translation.
Long time ago I could speak several kinds of strange tongue, even in the time when I was very mentally ill. So I thought it was spiritually dangerous to me and I stopped. It is not attractive to me anymore. Though I understand somebodies speak strange tongue privately but not very publicly.
In Beijing such a central city of China, many kinds of Style of faith group in CF (maybe primary) can be found. Fortunately free choice is an international principle.
Great you can go to Church and accept fellowship like that. When it comes to Church I always have a hard time. I hate classic Church going a lot, but I love open fellowship in God's loving truth and worship the very best with other believers, but not often in my Church for there only the important trained person may speak, and no one else can be inspired by the Spirit to add or challenge.
I've been in charismatic Churches as well and found the ones I went to loud, noisy and confusing. For like with you, lots of people were speaking in tongues, no one was interpreting and everyone was going through one another. I couldn't even hear the main person up front over the noise all around me. It was not to my liking.
Also I have spoken in tongues when psychotic. In ancient Hebrew, or so I thought, whole bible passages for days on end. Not only did I speak in tongues I also spoke with body signs. Ever seen a mad man dance, watch me when I go like that. Phew utterly amazing what bodies can do when psychotic that is for sure, and the endurance compared to 'normal' is astounding. Yet it didn't heal me from my psychosis, though I thought that is what God was doing at the time through me speaking in tongues like that. I have no idea what I been saying all those days and how much unclean spirituality would have entered me believing all the lies I did. Not good speaking in tongues was therefore my experience as well and I have shied away from it ever since.
However having said this, I do believe speaking in tongues can be from God. In the past Jesus has given me (and others with me,) some wonderful prophecies through people speaking in tongues, but then there was an interpreter. If people speak in tongues without an interpreter publicly
it cannot be from God, for unless they are just worshiping God by themselves. God's truth tells us how He displays His Spiritual truths in us and through us in accordance to the Word, not outside of the truths of Scripture, or only partially in the truths of Scripture, for then we do know how much we are speculating and how much is prophecy.
My experience with God's Spirit is that He always speaks very clearly and 100 percent truthfully in accordance to God's Word, (rather than religious traditions or how the harlot in us likes to see God's power displayed through us physically and publicly to bring our/her big ego self importance.) However God's truth is like lightening it lights up the darkness in us, rather than bringing about more darkness in us. Rather darkness usually means the Spirit has been grieved or pushed aside, not that He is speaking to us. If the Holy spirit does speak out of the darkness then it is about Christ's/God's/Life's suffering bad life and not anything else.
Interesting you also spoke in tongues when psychotic brother and found it a bad experience. Interesting how you also shy away from people using God's gifts unscripturally. 1 Corinthian 14 is clear enough isn't brother when it comes to worshiping God rightly in Church speaking in tongues. I much rather understand what is being said when I worship. For then I praise God not just with my spirit, but with my mind as well. I think this is really important in our worship of God - that we are in His revealing light and not in more darkness.
Peace.
