I understood why you made the mistake in #15. That's not what I'm asking about. But what you said in #161 is not compatible with what you did in #15. In other words, what you did in #15 shows that merely claiming to be "bought by Christ" is, in fact, not sufficient to be a Christian, in your view. The person must also, as you just said, not deny the divinity of Christ, and must not claim that he is saved not by Christ but by his own works.
So it is not as simple, in your view, as claiming to be bought by Christ.
JWs do claim to be saved by Christ, however. They believe works are necessary too, but I have never heard a JW deny that he is saved by Christ.

A JW would deny that YOU have been saved by Christ because YOU are not a JW.
JW's (like some Catholics) are hyperdenominationalists who think that they and they alone are the exclusive purveyors of truth on this planet.
I don't make that claim for myself or for my church. Jesus Christ alone is truth. To know Christ is to know Truth.
