Catholicity is a strong component of Archbishop O'Hara High School, the largest of four diocesan high schools in the Kansas City-St. Joseph Diocese.
     Themes are created for each year. These themes are Lasallian-influenced, and they focus on peace and justice and permeate the liturgies, daily prayers and actions of the community.
     Students have a myriad of opportunities to live out their faith by planning and participating in liturgies, attending retreats and volunteering for service opportunities through Lasallian Youth, Student Council and National Honor Society. Many students go beyond the yearly requirements for service and are recognized in the larger community for their amazing efforts.
     Members of Lasallian Youth strive to live out the ideals of St. John Baptist de La Salle – Faith, Service and Community. they explore their faith as young adult Christians through service and reflection. They serve the needs of their community by volunteering to work in soup kitchens, parishes, tutoring and recreation programs, transitional housing, residences for the elderly, and other programs that assist those who would otherwise be neglected.
     Food and clothing drives as well as collections for the missions give students a tangible way to help those in need. Most importantly, students take wit h them when they graduate from Archbishop O'Hara, the notion that service is a part of life. Giving selflessly to others is to follow in the footsteps of Jesus.
