On Christ Being Sacrificed Once and For All

St. John Chrysostom ca. 349-407

What then? Do not we offer every day? We offer indeed, but making a remembrance of His death, and this [remembrance] is one and not many. How is it one, and not many? Inasmuch as that [Sacrifice] was once for all offered, [and] carried into the Holy of Holies. This is a figure of that [sacrifice] and this remembrance of that. For we always offer the same, not one sheep now and tomorrow another, but always the same thing: so that the sacrifice is one. And yet by this reasoning, since the offering is made in many places, are there many Christs? But Christ is one everywhere, being complete here and complete there also, one Body.  As then while offered in many places, He is one body and not many bodies; so also [He is] one sacrifice. He is our High Priest, who offered the sacrifice that cleanses us. That we offer now also, which was then offered, which cannot be exhausted. (Homily 17 On Hebrews, 6)
