Commemorations are underway regarding the 300th anniversary of the canonization of Saint Stanislaus Kostka, the Jesuit patron of Polish youth. 

In September 2026, a relay pilgrimage organized by the Diocese of Płock concluded in Rome. Approximately 160 to 200 participants traveled 1,700 km from Vienna through Austria, Germany, and Italy to reach the Church of Sant'Andrea al Quirinale. During the conclusion of the journey, Pope Leo XIV addressed the pilgrims, encouraging them to make bold life choices in service to God. 

In Siedlce, the Catholic Youth Association (KSM) also held a mass to honor the saint. Local clergy and youth members highlighted Kostka as a model of perseverance, noting his historical determination to pursue a religious vocation despite significant opposition from family and friends.
