I am somewhat connected to an AMiA congregation, and while they are conservative they are really far from Reformed. They recite creeds each week, but they are not really confessional (even to the 39 articles), don't hold to the doctrines of grace, liturgy is somewhat reformed in structure but the preaching and singing are not reformed. I saw the bishop once speak "in tongues". And the pastor has been receiving his theological training from what he described as and anglo-catholic perspective (he did say he is not crazy about it though.)
Most of the good folks in this congregation have come from charismatic backgrounds and are finding more depth (esp. in the historical nature of their liturgy) here than they've ever experienced. And I'm glad the Africans have stood up and fought for the authority of scripture. This is a good starting place for reformation, but there is still a lot of work to do.
