Down in Sevierville, Tennessee is a branch of the Church of God you may never have heard of. This isn't just some guy pounding away on his keyboard (ahem), but a real little group which claims up to seven small fellowships (6 in the US and 1 in Canada). As with most such groups, their website doesn't give much away about exactly where they popped up from, but it's a splinter from the Garner Ted Armstrong wing of movement (CGI or ICG) going back about ten years. Like most related churches they seem to serve a declining older demographic that remembers the halcyon days of Herb and Ted.
Some sections of their website seem to be poorly updated, but it is still active and they currently promote themselves with a small ad on Alan Ruth's biblestudy.org. George Trent is president and author of their Quarterly Letter. They will be holding their 2016 Feast of Tabernacles in Pigeon Forge, Tennessee. Their previous FOT in Lexington, Kentucky didn't appear in the list published by The Journal.
It seems pretty standard Armstrongism. Nice shield logo but nothing much to show in the way of printed materials, magazine or broadcast media. Not to be confused with COG Worldwide Ministries.
