Theodoret of Cyrus: Christ Died to Overcome Original Sin

For this reason he is the mediator of a new covenant so that those who are called may receive the promise of the eternal inheritance, now that the death has occurred for redemption of the transgressions under the first covenant (v.15): he accepted death for all for this reason, that he might accord salvation also to those fallen under the curse of the Law on account of the Fall, and render them sharers of the eternal goods.
