A golden bell and a pomegranate, a golden bell and a pomegranate, upon the hem of the robe round about.

Gregory The Dialogist
AD 604
Hence in the vesture of the priest, in accordance with the divine Word, pomegranates are added to the little bells. What else is symbolized by pomegranates but the unity of faith? For as in the pomegranate many seeds within are protected by one outer rind, so unity in faith comprehends numberless people of holy church, who, though varying in merits, are retained within it.
