Jesus was definitely an apostate. He healed on the sabbath, and encouraged others to deviate from the laws. Love your god, and your neighbour was his main theme. Even JW's acknowledge that Jesus brought an end to the Mosaic laws. Can't get much more apostate than that! So by OT definition, Jesus was an apostate. CT Russell was an apostate. Rutherford was an apostate. The majority of JWs today were in other religions, that they turned their backs on and now denounce. They are all apostates. So am I, and I reiterate that following the course of Jesus can't be a bad thing.
JW's have to get past their arrogance and realize that they do not have a monopoly on the concept of apostacy.
