I don’t really have a scripture based response, just that I grew up in a church that had no membership and they was no fuss, no muss with backbiting and fighting. Then I move to TN and “you gotta join the church you attend,” I was told over and over; well the two churches I did “join,” the pastor used my membership against me with, “you’re a member of this church, and you’ve got to stand behind me.” If they were behaving right, they wouldn’t need anyone to stand behind them.
I do not believe that church membership is a God-thing, I believe it was orchestrated by man to control what he thought were “his” sheep instead of “God’s” sheep and then they started getting big with handling lots of money, so then they had to control the denomination.
But that’s just me. My experience has been that God keeps track of who goes where and does what. But it’s hard for people who have never experienced a membership-free church to understand how blessed an experience that is.
God bless,
