The Nordic Catholic Church, with St. Johannes Døperen Kirke as its parish church and cathedral, is a spiritual home for a diverse congregation that includes members from all over Eastern Norway. The church functions as a meeting point for believers, where a number of activities and services are offered. Every Sunday the Holy Mass is celebrated at 11, which allows for fellowship and worship.
In addition to church services, the church organizes theology days with lectures and talks, which give members the opportunity to immerse themselves in faith and theology. Bishop Ottar Mikael has also been active in the congregation, including conducting visits and consecrating holy oils. The church emphasizes prayer networks and offers book sales, as well as focusing on finding God in nature, which can enrich members' spiritual lives.
