I have never studied Hebrews deeply; by which I mean that I never had the opportunity of teaching it as a text for A-level ... that's the best way I know of really getting into a text; examining it daily with ones students for an entire year. But I was aware that sharp critical eyes have wondered why a Letter about the Sacrifice of Christ nowhere mentions the Eucharist. But, some time ago the text of Hebrews 13:10 hit me in the eye. "We have a place of Sacrifice [thusiasterion*] from which those who serve [latreuousin] the Tabernacle have no right to eat". Which clearly implies that 'we' do eat of a Thusiasterion which we do 'have'. [S Ignatius used thusiasterion in a Eucharistic sense.]
There is an always-thought-provoking Methodist scholar called Margaret Barker who sees Hebrews as an exposition of the Eucharist as the New Temple; she points to 12:22-24 as a summary of its theology as the synaxis of the Christians with the whole Company of Heaven.
CUT to the sands of Egypt. Where great mounds of ancient rubbish have yielded scraps of papyrus which have been preserved by the dryness of the desert. Thousands of these, excavated more than a century ago, are in the cellars of the Ashmolean Museum here among the Dreaming Spires. And they give us a fresh insight into everyday life in the Greco-Roman world. They include a large number of invitations to the deipnon of a God at his Temple, making it clear that the feast following the sacrifice was, in ancient religion, an integral part of the sacrifice itself. This is why Temples very commonly had, as part of their complex, kitchens and dining rooms. And it is also the reason why S Paul is so concerned (see I Corinthians ... which I have taught) about his converts' dining and eating habits. The religious and the social mingled so closely that it could be very easy to find oneself inadvertently committing idolatry by what one ate, and where.
It is clear to me that Hebrews 13:10 refers in passing to just this connection. The Lord's Table is one with the Altar on High where the Lord eternally pleads his Sacrifice. We eat from this Altar of Sacrifice at the Eucharist. But the non-believing Jews still (as the Author of Hebrews writes his Letter) frequent the sacrifices which the Lord abolished in the combined events of the Cleansing of the Temple, the Last Supper, and Calvary. And they, he points out, logically have no right to eat of his Thusiasterion, which is to say, of "our" Eucharist.
