Pope Francis has joined Instagram under the username ‘franciscus'. His first photo pictured him at a prayer benchwith the simple caption “pray for me”, which, given the nature of internet commenters, may be a useful plea.

The caption to the pontiff's account bears the quote: “I want to walk with you along the way of God's mercy and tenderness.”
