"why believe Herbert Armstrong and his son?"
I believe the Bible, chapter and verse, and you haven't given me ANY chapter and verse that supports your pagan worship!
It's not Herbert Armstrong and his son that you have to refute.
It's those references they use, and those historical references, that you have a problem with.
And those references are time-tested, and as solid as the Rock who put them in the Bible.
“my pagan worship”
hmm, that’s interesting, care to back that up?
paganism is the worship of false gods, are you saying the Father, Son and Holy Spirit is a false god?
