St. Theodore the Studite: Since then the only-begotten Son of God has been sent...

Since then the only-begotten Son of God has been sent from the Father as propitiation for the world, may we, the blind, see again, we captives be freed, we oppressed be forgiven. 

Who is blind? 
One short-sighted through attachment to the passions. 

Who is captive? 
One led away by unseemly thoughts. 

Who is oppressed? 
One broken by sins. The Lord heals them; for he is a physician of souls as well as bodies. . . 

Let no one then remain unenlightened and unhealed, but let them draw near with faith and they will receive blessing from the Lord, and mercy from God their Saviour [Ps. 23:5].

St. Theodore the Studite
