I know, the Rublev Trinity is the ultimate hospitality icon, but I posted it recently, and it occurred to me today that the Martha and Mary household with its visit by M&M's friend Jesus, a regular guest, would do nicely for a scene of a shared meal. I also looked for a good icon of the Emmaus story but didn't like the He Qi painting very much; it seemed dashed off and hasty and the two travelers were male, which isn't at all clear in the story. (New Testament scholar John Donahue, S.J. has argued convincingly that one of the Emmaus two was female. He's not the only one.)
Remember, though, not to let Martha and Mary play competitors in your head. For a reminder, see here.
