St. Stanislaus Kostka is considered to be the patron saint of youth, young students, and seminarians. He is also invoked for broken bones, heart palpitations and serious illness. He is sometimes depicted receiving Holy Communion from the hands of angels; sometimes receiving the Infant Jesus from the hands of the Virgin. His tomb is located in the church of San Andrea del Quirinale in Rome. A young Fr. Karol Wojtyła, later to become Pope John Paul II, would often stop to pray there during his doctoral studies in Rome.

Prayer to St. Stanislaus Kostka

I rejoice with thee in that singular gift of virginal purity which graced thy spotless heart; and I humbly beseech thee, obtain for me the strength to overcome temptations to impurity, and inspire me to continual vigilance in keeping intact the virtue of holy purity.
