The Circumcision of Jesus

I'm preaching in a series on the life of Jesus at Trinity College, Cambridge this Sunday evening (6.15 if you are in the area and want to come!).
The topic I've been given is the 'Naming and Circumcision', and I was asked to choose a picture to speak to. I've chosen this Fra Angelico version.

I will blog the sermon after it is delivered (and it will go up on the Trinity Chapel website too), but in the meantime here are my headings:

Saviour
Crucifixion/Communion
Jewishness
Inclusion/Exclusion
Masculinity (and Libby Lane's consecration)

All in 12-15 minutes!
