John 20:12

By all these circumstances, as though a door was being opened for her, she was led by little and little to the knowledge of the Resurrection. And the manner of their sitting invited her to question them, for they showed that they knew what had taken place; on which account they did not sit together either, but apart from one another. For because it was not likely that she would dare at once to question them, both by questioning her, and by the manner of their sitting, they bring her to converse.

And therefore she received no small reward for this her great zeal. For what the disciples saw not, this saw the woman first, Angels sitting, the one at the feet, the other at the head, in white; even the dress was full of much radiance and joy. Since the mind of the woman was not sufficiently elevated to accept the Resurrection from the proof of the napkins, something more takes place, she beholdeth something more; Angels sitting in shining garments, so as to raise her thus awhile from her passionate sorrow, and to comfort her. But they said nothing to her concerning the Resurrection, yet is she gently led forward in this doctrine. She saw countenances bright and unusual; she saw shining garments, she heard a sympathizing voice.

(Tr. cxxi) But why did one sit at the head, the other at the feet? To signify that the glad tidings of Christ's Gospel was to be delivered from the head to the feet, from the beginning to the end. The Greek word Angel means one who delivers news. (de Con. Evang. iii. xxiv) Here the Angels must be understood to rise up, for Luke describes them as seen standing.

For look she did, "and saw two angels in white, sitting, the one at the head and the other at the feet, where the body of Jesus had lain." Why is it that one was sitting at the head, and the other at the feet? Was it, since those who in Greek are called angels are in Latin nuntii [in English, news-bearers], that in this way they signified that the gospel of Christ was to be preached from head to foot, from the beginning even to the end?

(Hom. xxv. in Evang. c. 1, 14) The Angel sits at the head when the Apostles preach that in the beginning was the Word: he sits, as it were, at the feet, when it is said, The Word was made flesh. By the two Angels too we may understand the two testaments; both of which proclaim alike the incarnation, death, and resurrection of our Lord. The Old seems to sit at the head, the New at the feet.
