That was another of my issues with the AoG - there was no doctrinal consistency from one body to the next.
I grew up in the AG - third generation on my mother's side. My deceased brother was an ordained AG pastor. I gave up the AG when I realized that, as a denomination, they didn't know what they believed. The best I could come up with as a statement of faith was "Don't drink, don't smoke, don't cuss, and don't tolerate those who do."
From the AG website: These are nonnegotiable tenets of faith that all Assemblies of God churches adhere to. This list is derived from the official Statement of Fundamental Truths.
Certainly there are congregations who don't live up to that, just as there are errant congregations in just about every denomination.
But I believe you err in painting the entire denomination with a broad brush, much the way the author of this article errs in his interpretation of evangelicalism.
Your mileage may vary.
"Don't drink, don't smoke, don't cuss, and don't tolerate those who do."
What about the most important part: "don't go with girls who do." ;-)
