In medieval legend, griffins not only mated for life, but if either partner died, then the other would continue the rest of its life alone, never to search for a new mate. The griffin was thus made an emblem of the Church's opposition to remarriage. Being a union of an aerial bird and a terrestrial beast, it was seen in Christendom to be a symbol of Jesus, who was both human and divine. As such it can be found sculpted on some churches.
