In broader terms, there is benefit in belonging to a specified network of relatively like-minded ministers. It is true that we all belong to the Church universal, but if that is the only group of church leaders we belong to we will belong to nobody when push comes to shove. We are human and we need support, friendship and fellowship on incarnational, not theoretical, levels.
But with denominational specificity comes doctrinal specificity. And here, there arise a handful of issues. Through the years I have wrestled with a few things: the culture of my denomination as opposed to its theology, doctrinal specifics my denomination has traditionally regarded as central that I do not, and a few specific areas of potential disagreement with the statement itself.
As to the culture of the Assemblies of God, there is a broad spectrum of church expression given the missional and entrepreneurial DNA of our denomination. But that does not mean that there have not been times in my ministry life when leadership has strongly implied that if I am not doing things their way I am doing them wrong. But as a wise leader once told me, "The beauty of the AG is that I can listen to those things and then go home and do church the way God built me to do church." This piece of advice kept me from leaving more than once while I listened to cultural pressures from pastors different from myself.
As for doctrinal disagreements, my study and convictions have aligned me with our Statement of Fundamental Truths, though my sense of what is primary is a little different than our traditional formulations. This does not keep me from being a part of the AG. What it does is provide an encouragement to be a part of the theological growth of the movement. If I agree broadly and feel there are areas of growth in specifics, why not be a part of the movement and help build it from within? I don't know of a reason not to.
I went ahead and renewed again this year, and I think it will be a good thing.
