While the PCUSA has been debating the inflamatory issue of ordination of gays and lesbians, our brothers in the PCA have been debating whether their Book of Order allows ordination of deaconesses. This according to the Layman. Not that I find the Layman a particularly unbiased or even factual reporter of events. (At a General Assembly four years ago, I was at an event that Parker Williamson, founder of the Layman, reported on. We evidently were at two different events.) I usually read it to keep up with my friends. My friends on the progressive end get written up and dissed.
It is my understanding that for the EPC, ordination of women is a local option, but I'm not sure about that. PCUSA churches leaving for the EPC are migrating to a nongeographical presbytery where their ordained women can retain their ordination.
I never encountered either PCA or EPC until I moved south. The largest Presbyterian churches in Memphis are either PCA or EPC. Mega churches.
