It should be emphasized that St. Casimir is a saint for today. In his personality we see character traits that are of immediate interest for us today. First of all, his sanctity is such quality as to unite nations. We are reminded of Poland’s multi-nationality and her multi-challenges and multi-unions. Practically all of the ruling nations in Europe are connected with the Jagiellonian Dynasty, and therefore St. Casimir is closely related to them. Secondly, St. Casimir is an example of a strong religious piety especially with regard to his love of the Divine Presence in the Blessed Sacrament and toward the Mother of God. The many paintings of this saint are legendary, in particular the iconographs of the Prince in kingly robes, kneeling before the doors of a cathedral. When, on the occasion of his canonization, his tomb was opened, beside the head of the Prince was found a parchment on which was printed a beloved hymn in honour of the Mother of God: "Omni die dic Mariae..." translated: "Honour Mary every day..." but sounds even more beautiful when translated as: "Every day say to Mary...". Are not the love of God’s Mother and the loving devotion to the Eucharist strong arguments for Prince Casimir being known universally as a "true Pole" and one having a "post-Vatican" religiosity! Thirdly and finally, our saint is an example of diligence and self -education. In these days such traits are greatly needed for our youth - to achieve a solid education and to demand it from oneself.
The history of Poland notes many kings by the name of Casimir, but it must be stressed that almost every one of them obtained his sobriquet from his contemporaries. But, Casimir the Reformer, Casimir the Just, Casimir the Great, Casimir Jagiellonczyk and Jan Casimir who went down in history as the author of Vows pronounced to the Mother of God. Of these beautiful titles, the most beautiful bears that shining title: "saint" which Prince Casimir aptly radiates.
