At St. Peter School, faith becomes living, conscious, and active though instruction and participation in prayer, worship, and sacraments. St. Peter School is one of the oldest continuously operating Catholic elementary schools in the original city of Washington, DC, and currently operates under the auspices of the Archdiocese of Washington as a regional Catholic elementary school supported by the local parishes of St. Peter's, St. Joseph's, St. Dominic, St. Mary Mother of God, St. Patrick's, and the Cathedral of St. Matthew the Apostle.
Catholic faith and values are integral to instruction at St. Peter School. A Catholic virtues program is central to the culture of the school, and all students participate on service projects at least once each month as an expression of the school's mission.
Students learn about and experience the Catholic faith in a variety of ways. First and foremost, all students have regular, focused religious instruction. Students learn about the Old and New testaments, the Ten Commandments, the life of Jesus, the lives of the saints, and the theological underpinnings of the Catholic sacraments. Middle school students also explore Catholic social teachings with the guidance of the legion teacher and the parochial vicar, who encourage faith formation through authentic questioning and self-examination.
As a school community St. Peter's regularly celebrates Mass and comes together for events to mark the special liturgical seasons of the Church. Every Wednesday of the school year, students lead a Mass, and the entire community, including students, teachers, administrators, and parents, attend worship together.
