Unveiled is the new papal coat of arms. There is much fuss over how simple it is but then again, the best arms are simple. You may remember that when John Paul II arms were revealed there was a bit of consternation for he had put a large letter "M" on it to represent "Mary" - a huge no-no in the world of heraldry. There is general agreement that this coat of arms is a success.
The shield itself is blue, most often associated in the Church with Mary though in it also stands for steadfastness and fidelity. Center top is a sun which we can see easily represents THE Son, Jesus, for the IHS (IHSUS - the first three letters for Jesus in Greek) the Cross, and the three nails which represent the three nails that held Jesus to the Cross. This symbol incidental also is the symbol of the Jesuit order.
On the lower left hand corner is a gold star which represents Mary and in the lower right is what looks like an upended bunch of grapes but what is actually a nard flower. Nope, I never heard of it either. I looked one up and so present it here. Apparently it represents St. Joseph though I dare say I don't know from where this comes. It is not in my books. I would love to know the source if anybody knows.
Anyway, from this we can see the pope's love of the Holy Family and perhaps an aim of his papacy - to safeguard the family. Time alone will tell.
By the way, his motto is Miserando atque eligendo, from a homily of Saint Bede. It is Latin for "Having had mercy, He called him" This is a reference to when Jesus called Matthew to be one of his apostles despite his being unworthy.
