Jan Wojciech Balicki was born on 25 January 1869 in Staromieście (now part of Rzeszów), Poland, into a poor and deeply religious family. His father Mikołaj (Nicetas), a railway trackman of the Greek-Catholic rite, and his mother Katarzyna (née Saterlack), a Roman Catholic, raised their children in both traditions yet had Jan baptized the day after his birth in the Latin rite; his godparents laid him before the altar and offered him to God for the priesthood. He had three brothers and three sisters. From childhood he was known for diligence, purity, and a serious love of truth.
After schooling in Rzeszów he entered the diocesan seminary of Przemyśl in September 1888. Having obtained the necessary permission from the Holy See regarding the rite of his ordination, he was ordained priest on 20 July 1892. He celebrated his first Mass in Świlcza and was sent as curate to the parish of Polna, where for fifteen months he gained renown as a gifted preacher and confessor; crowds came from far and near, and parishioners later testified that he penetrated hearts so deeply that people wept and hurried to church with joy.
In 1893 he was sent to Rome for higher studies at the Pontifical Gregorian University. There he earned degrees in philosophy and canon law and a doctorate in theology, immersing himself especially in the thought of St Thomas Aquinas. In his free time he visited the churches of the saints and apostles and discovered that true learning leads the soul to God. Returning to the diocese in 1897, he was appointed professor of dogmatic theology in the seminary of Przemyśl. His teaching was marked by profound faith and love for the Truth; he sought wisdom and the light of the Holy Spirit above all in prayer. He served as prefect of studies (1897–1900), later as vice-rector, and from 1928 to 1934 as rector. Ill health forced him to resign his offices in 1934, yet he continued to live at the seminary as confessor and spiritual director to the seminarians. Among those he formed were Blessed Władysław Findysz and the Servant of God Stanisław Kołodziej.
Beyond the seminary he was a sought-after preacher of missions and retreats, confessor at the cathedral and to the Discalced Carmelite nuns, hospital chaplain, and visitor of the sick in their homes. He founded a house of refuge for prostitutes and was called "the apostle of the poor." He spent himself without reserve, uniting contemplative prayer with apostolic charity, seeking out those who had strayed from Christ's flock and helping neighbors in both material and spiritual need.
In the second half of February 1948 he was diagnosed with bilateral pneumonia and advanced tuberculosis. He died in hospital in Przemyśl on 15 March 1948 in the odor of sanctity. Crowds came to honor him; after the funeral on 18 March he was buried in the Cathedral of the Assumption of the Blessed Virgin Mary and St John the Baptist, where his remains still rest. Already in 1975 Cardinal Karol Wojtyła wrote to Pope Paul VI asking that Balicki be proposed as a model for priests of the modern age. Declared Venerable in 1994, he was beatified by Pope John Paul II in Kraków on 18 August 2002.
May Blessed Jan Balicki obtain for us the grace to unite prayer and apostolic charity, and let us imitate today his humble love of truth and mercy toward every soul.
