Why does it have to be either or?
I've been to Pentecostal Churches where the Spirit of God did move, but the emotional aspect of their comprehension often resulted in a rather shallow less a less stable faith, and people did come and go more so than in more traditional churches.
I've also been to Baptist Churches that are known more for their Biblical teachings and have found people more stable in the faith because they are founded on the Word of God more so than than Pentecostal tend to be.
The Spirit of God lives in His Word and moves more through sound teaching of the scripture than emotional displays. But I still love the Pentecostal Church.
It doesn't have to be either...I was just stating extremes for the sake of making a point. The point being, I would rather be in a church where freedom of the spirit is encouraged as opposed to one where man is in control. If, because of that freedom , there is an occasional person who abuses it, I would prefer that to one where the service is so scheduled, managed, and controlled that the spirit is given no place to move.
Freedom is inherently messy...politically and religiously...but in both cases I would much prefer it to the alternative.
Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom.
