That’s true. Ordinarily there is always room for forgiveness and charity in that regard, but in this case, we should perhaps ask ourselves whether our decisions to overlook these watchtower transgressions (to put it lightly) is in fact an act of condoning their actions. The command has always been to “get out of her my people” and so that puts upon us that a degree of discernment is required from us in that those of discernment are required to act - rather than tolerate, overlook (transgression) or to not perceive motive, if we wish to demonstrate our understanding through loyalty. In fact, putting up with it is not dissimilar to a battered woman hoping her husband will change. Why does she stay? The motives are numerous, usually one of sacrifice to her children, but the outcome - has it ever been good? Only if the perpetrator sees the error of his ways and wishes to change because he understands what he is. As the scripture points out that as his very existence is destined to be one of opposition, we are told that this is not going to happen.
We are all flawed in our service to Jehovah. When has our putting up with our flaws ever been acceptable to Jehovah, and the more-so, if we choose to overlook them in ourselves? We are told to “endure” the trial of self correction; to be constantly upon the watch, not only for the kingdom, but against ourselves and our own proclivities. If it took the sacrifice of Christ for us to be given a way back, then clearly there must be an active desire in us to discern what is required of us. It begs the question; is our degree of tolerance an indicator of and in, the values in our faith? What measure are we verifying our faith with?
