Supreme Pontiff of Time

The Supreme Pontiff of Time, also known as the Time Pope, was a religious position among the Time Lords and was a rank held by the leader of the clergy on Gallifrey. In an alternate timeline where Gallifrey was destroyed and the Doctor was exiled to Earth, the Time Pope was decapitated during a revolution on the Gallifreyan homeworld which saw several Cardinals also executed.
