I'm glad you're doing research Makersmark.
One thing I often wondered. If Jesus came and decided Russell had it right and chose his brand of faith then why would anyone believing what Russell belived today be branded 'apostate'. This doesn't make sense. How can the system of faith that Jesus HIMSELF approved now be wrong?
...........and 'New Light' doesn't cut it for me.
That Proverb about the light getting brighter was advice from a Father to a Son. If my Dad had taught me how to prepare food so I don't get poisoned and then kept changing the recipe because he kept getting it wrong, I'd either have died of food poisoning early on or given up and asked someone else.
So, I did ask someone else as the watchtower poisoned me!
