The Council of Trent of 1563 enjoined bishops to instruct their flocks that "the holy bodies of holy martyrs ... are to be venerated by the faithful, for through these many benefits are bestowed by God on men". The council further insisted that "in the invocation of saints, the veneration of relics and the sacred use of images, every superstition shall be removed and all filthy lucre abolished." There are also many relics attributed to Jesus, perhaps most famously the Shroud of Turin, said to be the burial shroud of Jesus Christ.
