Reverend Timothy Tarnacki, O.S.P.P.E. is a priest of the Order of Saint Paul the First Hermit, also known as Pauline Fathers and Brothers. He was born in Poland and immigrated with his family to the United States at the age of 12.  He grew up in Stamford, Connecticut, and joined the Paulines by starting his postulancy after graduating high school in 2008.

Father Tarnacki attended the Pauline Seminary and the Pontifical University of Saint John Paul II in Krakow, Poland. He graduated with a Master’s Degree in Theology, specializing in Biblical Exegesis. He made his final religious vows in 2015 at the Marian Shrine in Czestochowa, Poland. Most Reverend Andrzej Zglejszewski, Auxiliary Bishop of Rockville Centre, ordained him to the priesthood in 2016 at the National Shrine of Our Lady of Czestochowa in Doylestown (Bucks County).

Following ordination, Father Tarnacki began ministering at the Shrine. Since that time, he has been particularly involved with the Shrine’s youth and young adult ministry, being the co-founder of Czestochowa Young Adults (CYA) Group. He has also served in various capacities including Shrine media coordinator; chaplain and theology teacher for the Shrine’s homeschooling community; coordinator of lector and altar servers’ groups; and more.

Here are some interesting facts about Fr. Timothy:

1). St. John Paul II is his favorite saint and his vocation story is closely linked to JP2’s death!
2). Timothy is actually his religious name that he chose, being inspired by the two Letters of St. Paul to St. Timothy.
3). He loves playing sports, running, traveling and hiking in the mountains (the highest peak that he climbed so far was 14,278′).
