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).

Eucharistic Host with Rays: The Eucharistic symbol in this logo emphasizes that the Eucharist is the “source and summit of the Christian life (Vatican II, Lumen Gentium, no. 11). The Eucharist gathers the young adult community together and is truly in the center of it. “In the many transitions that young people face, they should be able to find a ‘home’ wherever Mass is celebrated (USCCB, Listen, Teach, Send). By pointing young people toward the Real Presence of Christ in the Eucharist and inviting them to active participation in a Eucharistic community, we offer young people an encounter with the Lord who is always present, mercifully understanding, and the source of all healing. (USCCB, Listen, Teach, Send)
Open Hands: Open hands are a symbol of prayer and openness to receive God’s grace. Hands that are lifted are a common Biblical image of prayer, “I will bless you as long as I live; I will lift up my hands, calling on your name” (Psalm 63:5). The open hands in gesture of prayer are a reminder for young adults that prayer is the foundation of a life of discipleship. As Pope Francis addressed the young people, he said to them: “Hope is nurtured by prayer. Prayer preserves and renews hope. It helps fan the spark of hope into flame.” Open hands are also a symbol of good works, especially done in service to others, as Jesus reminded us: “Whatever you did for one of these least brothers of mine, you did for me” (Matthew 25:40).
Shield Outline: The shield is often used in Christian iconography to represent faith. Portraying faith as a shield is a reminder that amidst spiritual and worldly battles, young adults can find their identity, belonging and strength in their relationship with the Lord, “the Lord is my strength and my shield” (Psalm 28:7). This symbol of a shield also invites young adults, as St. Paul wrote to the Ephesians, to “hold faith as a shield, to quench all the flaming arrows of the evil one” (Ephesians 6:16). By holding faith as a shield, young adults are reminded: “Please, do not leave it to others to be protagonists of change. You are the ones who hold the future!” (Francis, Christus Vivit, no. 174)
Dove: The open hands also resemble the shape of a dove. A descending dove is a common symbol of the Holy Spirit, as we learn in the Gospel of Matthew, that as Jesus was baptized, “the heavens were opened, and he saw the Spirit of God descending like a dove coming upon him” (Matthew 3:16). The Holy Spirit gathers young adults together in the Church and leads them on a mission, to become sent forth as missionary disciples. "Christ draws near to young people in order to listen to them, teach them, and send them forth, filled with the Holy Spirit to” (USCCB, Listen, Teach, Send) In this way, they can become, “protagonists of the revolution of charity and service.” (Francis, Christus Vivit, no. 174)
