(contact person: Sr. Concesa Martin)


All students attend Religion classes that explore the different dimensions of Catholicism, Protestant Christianity, and World Religions.


Mass is celebrated for High School, Middle School and Elementary School each week. Different classes prepare and participate actively in the service. Several times a year, on important occasions, we have Mass for the whole school community.


Prayer plays an important role in life at Seisen. Every morning groups of students lead the whole school in prayer and set the tone for the day. The school chapel is open everyday for private prayer, liturgical singing and religious class activities.


Catholic students, together with their families, are prepared for the Sacraments of First Communion and Confirmation.
