I have been called an apostate in the past week by my SIL, my stepdad, and my soon to be ex-wife. It didn't help that apostasy was featured in this past weeks WT study, a point my ex was quick to remind me...
I have done a quick search in the WT CD Rom to see how many times the word apostate or derivatives appear (I searched "aposta*").
Turns out that most of the references to apostate are in the OT, referring obviously to a deviation from Judaism. There are only 2 scriptures in the NT that refer to apostates. Let's look at each one:
(Acts 21:21) 21 But they have heard it rumored about you that you have been teaching all the Jews among the nations an apostasy from Moses, telling them neither to circumcise their children nor to walk in the [solemn] customs.
So Christianity was called an apostasy from Moses by Judaizer opponents.. hmmm... JWs today wouldn't call themselves that I'm sure... Well there must be hope in the next verse, right?
2 Thessalonians 2:3) . . .Let no one seduce YOU in any manner, because it will not come unless the apostasy comes first and the man of lawlessness gets revealed, the son of destruction.
Well, this scripture discusses the man of lawlessness, which as we know that the WTS applies to the clergy class. I'm not a member of the clergy, and I daresay that anyone on this board is either. So no apostates then...
This means that calling a person who leaves the JWs an apostate does not have a biblical basis. The next time you are called apostate (by a JW in an insulting way), ask them where the term apostate appears in the Bible and where does it refer to leaving JWs...
