Origen

“It is not only possible, but also the case that all rational creatures will eventually submit to one Law […] We profess that at a certain point the Logos will have obtained the hegemony over all rational creatures and will have transformed every soul to the perfection that is proper to it, when each one, exerting its own free will, will have made its own choices and reaches the state that it had elected. But we hold that it will not happen as in the case of material bodies […] it is not so in the case of illnesses derived from sin. For it is certainly not the case that the supreme God, who dominates over all rational creatures, can not cure them. Indeed, since the Logos is more powerful than any evil that can exist in the soul [πάντων γὰρ τῶν ἐν ψυχῇ κακῶν δυνατώτερος ὁ Λόγος], it applies the necessary therapy to every individual, according to God's will. And the ultimate end of all things will be the elimination of evil [τὸ τέλος τῶν πραγμάτων ἀναιρεθῆναί ἐστι τὴν κακίαν]. (CC 8.72)”
