Gluttony is not a reason to disfellowship. I can go to a buffet and eat 9 pieces of pizza and dessert and not gain any inches or weight. I do that because I can. And if I couldn't do that then I wouldn't. Which goes to self control.
I think that gluttony has more to do with greed and wastefulness. (Sure it is wasteful for me to eat 9 pieces of pizza in one sitting as it comes out the other end the next day, but then so does any fiber)
But others can eat a little and gain weight and inches. But they gain weight and inches and don't stop.
You CAN'T GAIN WEIGHT BY BREATHING. Eating must be done. It is a matter of self control.
If you are at a filling station and the pump turns off when the tank is full, the pump stops and you stop pumping. Then burn it up and that empties the tank and when the tank is low you fill up again.
Humans don't have that mentality with their bodies. They fill it up, don't burn it up and then fill it up again.
It is not an issue of disfellowshipping but as the original post said: "because of his greedy ways they may SHUN HIM....he may incur Gods displeasure and LOSE HIS LIFE...in the near future God will bring lawdefying GLUTTONS TO AN END.."
Yeah, we shun fat people because they are fat. We don't need an official announcment of disfellowshipping for that. Human nature does that. And yes they will lose their lives because it is unhealthy.
