Worldwide Church of God formally renounced and rejected Amstrong's teachings about 15 years ago. They are now accepted as as a normal and theologically solid denomination among Christian churches.
They dropped the legalism and the weird doctrines about Europeans being the lost tribes of Israel and such?
If true, that's good.
I had a stepmother when I was a kid who got really screwed up in the head by those folks.
Did you read their website? They don't believe in the military and/or the use of guns.
