Sisters of St. Casimir in Chicago, Lemont, Argentina, and Lithuania.
From the Legacy Room of the Sisters of St. Casimir:
St. Casimir Beloved Patron of the Sisters of St. Casimir
“You will be called Sisters of St. Casimir”
Thus proclaimed Bishop John W. Shanahan of Harrisburg, PA,
to Judith Dvaranauskas, Antanina Unguraitis, and Casimira Kaupas,
the three young women who became the first Sisters of the new congregation.
St. Casimir (1458-1484) - the son of Elizabeth of Austria and Casimir, the king of Poland and the grand duke of Lithuania - was born in 1458. His father introduced him to the art of governing, but as Casimir immersed himself in education and in religion, his actions became more God-centered. The wealth and prestige of the court did not entice him, but a life of love for God and charity toward those in need did.
The symbols associated with St. Casimir’s life, the lily, the sword and the crown, signify important aspects of his life. They have also become the symbols of the Sisters of St. Casimir and of the deep spiritual legacy of their patron — single-heartedness, the struggle against self-centeredness and injustice, and fidelity.
