A church that got full of itself is why Martin Luther eventually walked away, and why earlier on the Orthodox family of churches bid farewell to Rome. If it were not for the promise of God sustaining these pride-ridden worship bodies (and the problem persists to this day) they would have winked out. But it was not worldliness that kept them going. We will look in vain for a worship body that doesn’t have some badness. What we are well to look for is a local worship body where in spite of the badness, Christ visibly manifests in the life of the congregation, and it may be found to meet in some nondescript, homely place rather than some grand cathedral.
There is no other person or persons that can set you straight with the Lord other than yourself.
Those that find need of churches, I respect and understand, whatever it takes to bring you closer to the lord, but it is not my way.
