Who We Are

The Office for Ministry with Young Adults (OMYA) exists to help young adults connect, grow, and share their faith. It is one of three branches of the Office for Faith Formation for Youth and Young Adults (OFFYYA). The three branches of OFFYYA are: Office for Catechetical Formation, Office for Ministry with Youth, and the Office for Ministry with Young Adults. By being part of OFFYYA, these three offices hope to provide a better continuum of ministry and care that helps young people more easily transition from various stages in youth and young adult lives. While OMYA will focus on young adults ages post high school to 39, we are excited about collaborating with OFFYYA as a whole to create a more dynamic and interconnected web of ministry and outreach.

Fr. Stephen Delacy

Father DeLacy was born in Delaware County and attended St. George grade school and was involved with the CYO and then Msgr. Bonner High School, where he played soccer and basketball. He attended West Chester University for a degree in accounting and was associated with the Neumann Center, coached CYO Volleyball (where he won two championships but should have won three), and became the Youth Minister. After graduation, he worked for a year and taught CCD. Despite his great efforts to fight and resist God’s plan, he responded to God’s call to enter the St. Charles Seminary. He was ordained a priest in 2004 and was assigned to SS. Peter and Paul Parish while also leading retreats for the Malvern Retreat House and for Rachel’s Vineyard. He then served as the School Minister at Archbishop Carroll High School and Pope John Paul II High School. He was then appointed as the Vocation Director for the Diocesan Priesthood for eight years. In 2021, Archbishop Perez made him his Vicar for Faith Formation with Youth and Young Adults.

Fun facts about Father Delacy are that he has gained outstanding proficiency in conducting ice breakers and playing Beer Pong (with water). Father does not enjoy musical talent. You may contact Fr. DeLacy at fr.sdelacy@archphila.org or 215-587-3979.

Fr. Timothy Tarnacki

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′).
