I know both Falls Church and Truro, and have friends who attend there. These are FAR from "charismatic" congregations, rather they are classical evangelical churches who tolerate charismatics--which more "tolerant" liberal churches won't put up with.
The whole article is more balanced than the excerpt though and indicates that the charismatic movement brought these churches into the greater evangelical world. It is true, according to friends there, that most members are not "cradle to grave" Episcopalians" and bring a variety of theological opinions to their small groups. All the better though, as classical Anglicanism can really inform some of the less helpful parts of generic evangelicalism...the Lord is doing His work!
I wanted to post the entire article, but even though it was on VirtueOnline in its entirety, it was originally from WaPo and I didn't want to make trouble for JimRob.
