St Matthew-in-the-City is banking on a fallen angel - who some say is Satan himself - to help bring people closer to God.
The statue of Gadreel, one of the fallen angels in Enoch lore who reputedly led Eve astray in the Garden of Eden, was installed in the church's Peace Chapel next to the main altar on Friday, and will remain there for the period of Lent.
Vicar Glynn Cardy said the statue was to show that "even the devil would be welcomed in God's Kingdom".
"It's to show that no matter how distant you are, or even if you've fallen to your deepest depth - like Gadreel - you are still welcome to be in our midst," he said.
"Different people will feel differently when they look at this statue."
