In my Grandfather’s War Diary entry from Friday August 21 1942, he visits Jerusalem & Bethlehem. He said ” Left camp on trip at 8AM. Arriving at Jerusalem at 11AM. Straight onto Bethlehem – reaching Church of Nativity – star(?) & manger then to British War Cemetery.”
He most likely took (or purchased) these photos on this visit that day.
The comments under the photos are his own words from the backs of the photos.
14 Weeks Worth of Socks 
You know, for a girl who doesn’t believe in all that Christmas stuff, your Grandpa spent a lot of time in churches. Mine did too. He was an Anglican priest.
I can’t say he was particuarly religious when I knew him but perhaps he changed his mind or it was just a part of his life. My grandparents never went to church in the years I remember them.
I guess your Grandfather probably had too – being his job and all 🙂
