Peace,
So in essence what you're saying is if one does not "Believe" or subscribe to your religion then they are in fact worthy of slavery? Again, you're sounding very much like the slavemaster.
Faith is belief in something that is not proven to be actual fact. The concept of "true faith" or "worthy faith" is an oxymoron. You either know something or you don't and if you don't and believe in it anyway then you have faith. There is nothing true or worthy about faith because the very nature of faith is to not know.
Peace
Precise
Amen
