DEUSDEDIT (ADEODATUS) (Saint) Pope. (November 8) (7th century) The successor of Saint Boniface IV (A.D. 615). He ruled the Church for three years. Though little is known of the details of his Pontificate, his self-sacrificing devotedness to his flock during a year of pestilence endeared him to his people and ensured the veneration of his memory. He is said to have been the first Pope to append to his Decrees the leaden seals or Bullae from which the word Bull, describing them, has been derived.
