This makes no sense to me, Xzins.
[1] Everywhere else articles of faith and a confession are the same. I fail to see a distinction.
[2] How in the world do you "uphold and support" doctrines you do not believe?
[3] When in Cape Girardeau the nearby UMC church had a Oral Roberts grad as pastor and Reformed Seminary grad as associate pastor. The UMCchurch downtown had rank liberals as pastors. Who upheld what?
The articles of religion and a confession of faith are not the same. One is a denominational statement. The other is a personal confession. That is why many of us are part of the Confessing Movement. It is partially about ESTABLISHING a confession of faith within our denomination. That confession would then have to be written. In other words, they are viewed more creedally than confessionally. A creed is a general statement whereas a confession is a specific statement. For example, you might affirm the "Apostles Creed." However, you give yourself appropriate leeway in interpreting that creed to your situation. Take "from thence he shall come to judge the living and the dead." You interpret that premillennially, and other interpret it amillennially.
It doesn't mean you disavow the article.
How would an AOG reinterpret "tongue evidence?" I don't know. I'd have to see how they've written it; see how restrictive they've actually made it.
