Bruno was tried for heresy by the Roman Inquisition on charges of denial of several core Catholic doctrines, including eternal damnation, the Trinity, the divinity of Christ, the virginity of Mary, and transubstantiation. Bruno's pantheism was not taken lightly by the church,[2] nor was his teaching of metempsychosis regarding the reincarnation of the soul. The Inquisition found him guilty, and he was burned alive at the stake in Rome's Campo de' Fiori in 1600.
The Roman Inquisition still exists, though they have gone through a few name changes and are now called the Dicastery for the Doctrine of the Faith. They have the same goal, but they don't have as much power so they can't get away with murdering people anymore.
