Hey Douglas, your statement above recalls Deja vu to me, and for a second there I thought it was from the WWCofG hand book, but I don't mean this to be critical, just an observation.
I know that Herbert used to teach that being "born of God",1 Jn 3:19 and 5:18, proved that one could not be born of God until he was changed to incorruptible at the coming of Christ, have you heard this yet?
As I understand the United Church of God, no. I'm not sure what the doctrine of the Worldwide Church of God was.
