I think the world's largest Prebyterian church is in S Korea. Its probably about time they sent some missionaries back here to correct the PCUSA.
I am not sure but I've heard rumors they do send missionaries to the US. However, there are some very good presbyterian churches here, the PCA, the OPC and ARPC come quickly to mind. I would stay away from the Cumberland Presbyterians as well as the PCUSA. Those two are rather apostate, IMO.
I'm pretty sure that I read of one South Korean Christian missionary...
to Los Angeles/So.Cal. a few years ago.
