From when the 1981 Watchtower dealt with the Prodigal son, I was puzzled how they made it fit disfellowshipping.
To me it was saying that if you left God, not some church/organisation. Then you realised you had made a mistake and returned to Him. He was there waiting and watching for your return. There were no recriminations, you had come back to Him thats all that mattered.
Another parable that I always felt showed the real compassion of God was the Shepherd and the Lost Sheep.
A sheep strays gets lost and trapped . The shepherd sets off to find it, leaving the other 99 safe in the pen. They are ok they at that time don't need the shepherd because they are already safe and sound. The shepherd finds the lost sheep picks it up and carries it back to the rest of the flock. Celebrating that he found the sheep.
The Watchtower version would be that the sheep strays, gets lost and trapped. Its the sheeps own fault for leaving the flock(congregation) going off into the world and ending up in trouble. The shepherd/s (Elders) don't set off to find the sheep. They instead decide that the sheep should be ignored completly. If the sheep goes off like that its its own fault so we don't want anything to do with it. We will not allowed the rest of the flock tohave contact with it. If it wants to come back it will have to find its own way. If it does we will keep it in a separate pen for as long as we think it needs to be. And don't any of you other sheep dare speak to him.
