There would be personal reasons any go to a nondenominational church. I went early in my Christian life, after coming out of the Catholic church of my family that I was in for a few years when growing up, and a start among charismatic believers in fellowship, to nondenominational churches, at first following other believers I knew going to one, as I could not see any one denomination was right, and their differences were just divisive to Christianity. So faith with Christ in one's life and believing the revelation in the Bible were what I saw was important. I went to such churches for a long while, but later in life I tried a Christian church in the area I then moved into that was a Church of Christ then, though they did use instruments unlike Churches of Christ generally now, that church is since just a Christian Church in name. But I was then going to a Baptist church. I thought it was close to being the nondenominational belief as I understood in the teaching from the Bible. But there were differences, with authoritarian structure there, I left and tried going to a fellowship church that I learned then was a Nazarene church. But I went back to another Baptist church, where I stayed, this church, where I still went to until everything including this church closed down with the time of the spreading pandemic, did not stay Baptist in name, and now has a short name without any denominational designation, and there is never mention there now of being Baptist, the last mention was that the church is Baptistic. So in spite of moving toward being in a Baptist church I seem to be in a nondenominational one anyway. Who knows, is it God's moving, or not? I have some reasons to stay, though I can think of differences for which I would leave, but I don't think I will find a better church for me just now.
