Stanisław Kazimierczyk

Stanisław Kazimierczyk (born Stanisław Sołtys, 27 September 1433 – 3 May 1489) was a Polish Catholic priest and a professed member of the Canons Regular of the Lateran. He became noted for his ardent devotions to both the Eucharist and to his personal patron saint, Stanislaus of Szczepanów, as well as for his charitable dedication to the ill and poor of Kraków.

The canonization cause started under Pope John Paul II on 14 October 1986 and he was titled as a Servant of God. This came after previous attempts in the past to launch the process though the cause started at that time due to the personal intervention of the pope who was a cardinal at the time. That same pope named him as Venerable on 21 December 1992 at the same time he approved the beatification which was celebrated on 18 April 1993. Pope Benedict XVI later canonized the late priest as a saint of the Catholic Church on 17 October 2010 in Saint Peter's Square.

Life Stanisław Sołtys was born 27 September 1433 in Kraków to Maciej Sołtys and Jadwiga. His parents had long wanted a child and he was born on exactly the same date that the remains of Stanislaus of Szczepanów were being moved. His parents were members of the Brotherhood of the Blessed Sacrament. He preached in strong defense of the doctrine of the Real Presence in the Eucharist against the preachings of the Polish followers of John Wycliffe and Jan Hus. It was due to this that he gained the title "Apostle of the Blessed Sacrament". Saint John Cantius – a colleague of his at the Jagiellonian and a major scientist of the period – was a close friend of his.

The priest fasted numerous times and kept vigils on several occasions. He slept little and often slept on the ground more as a penitential act. On one occasion he went to visit the tomb of his patron saint when he saw the Mother of God with the Infant Jesus in her arms; Saint Stanisław and other saints were around her. 5 May – commemoration in Poland
