When I was trekking in Ethiopia a few years ago we passed a coptic church in the middle of the countryside on top of the plateau. The priest was walking along the track and stopped to greet us. He was happy for me to take a photo; something I don’t often do as I’m always a little embarrassed to ask. I was so taken by the calm and peace of this man that it was only later when I looked at the photo, that I really saw the beauty of his age etched face and rheumy eyes. I wondered what those eyes had witnessed in his lifetime.
