Theodoret of Cyrus: Salvation is the Outworking of God's Eternal Plan

Given to us in Christ Jesus before the eternal ages, but now revealed through the coming of our Savior Jesus Christ (vv.9-10): while the God of all determined these things even before the ages, he now pouts into effect what had been determined. In planning them he had Christ the Lord to concur with him, and in effecting them he had him as collaborator: through his coming he brought the work to completion.
