Apart from the background, the shield of Pope Francis’ coat of arms is the same as the one he used as archbishop of Buenos Aires. Such displays of heraldry offer a hint at a person’s identity and priorities, and so it is with the Holy Father.
The sun with the logo ‘IHS’ refers to the Jesuit Order, to which Pope Francis belonged. The two lower emblems, the star and the spikenard flower (so not a bunch of grapes) refer to the Blessed Virgin and her spouse, Saint Joseph. Both saints rejoice in a special devotion of Pope Francis.
The motto underneath the shield is also unchanged: “miserando atque eligendo” comes from the holy Venerable Bede’s homily on St. Matthew’s calling by Christ. Rather longer in English, the Latin phrase means “Because he saw him through the eyes of mercy and chose him”. This fits quite well with how we have come to know Pope Francis. No matter what we do or who we are, Christ chooses us because He regards us with mercy and that is a transformative act. Divine mercy makes us worthy to answer the Lord’s call.
The mitre and keys behind the shield are symbols of the power and duties of the papacy. Following Pope Benedict XVI, Pope Francis is the second pope to not feature the papal tiara on his coat of arms.
