Theodoret of Cyrus: All People Means Both Masters and Slaves

Then he brings out the purpose of the divine Incarnation. You see, the grace of God that brings salvation to all people has appeared, instructing us to renounce godlessness and worldly desires, and to live a life of self-control, righteousness and godliness in this present age (vv.11-12). This is the reason the only-begotton Son of God became flesh, to grant salvation to all people, both masters and servants, by causing them to abandon a lawless life in addition to godlessness. He gave us a glimpse also of the straight and narrow, bidding us live in godliness and self-control.
