"...For this son of mine was dead, but now he is alive; he was lost, but now he has been found." And so the feasting began. -- Luke 15:24
The Massketeers talk a great deal about sources of the self, ontology, personhood and the like. The New Testament word for substantiation is ousia (Gr. Ion. that which is one's own, one's substance, property). Jesus makes clear that one's substantiation comes solely from the Father in this parable. It can't be clung to or wrenched away from Him and taken elsewhere as a personal possession.
It is only in returning to his Father that the prodigal son regains his original status, his sonship. Contrition, remorse, repentance and penance return us to right relation with the Source of our very being.
