[2] Although the church was formally established in 1916, almost ten years after the beginning of the movement in Norway, it had already been holding services in a number of rented locations since 1910.
The church has always held a central place in the Norwegian Pentecostal movement due to its origins and size.
The church's building on St. Olavs gate, the so-called "new" Filadelfia, was consecrated in 1938, after an extensive renovation.
Through the Pentecostal Foreign Mission of Norway, the church supports mission work in the Democratic Republic of the Congo (through Communauté des Églises libres de Pentecôte en Afrique or CELPA, the Association of Free Pentecostal Churches in Africa), the Philippines, India, and the Middle East, among other areas.
Some of the most active missionaries sent or supported by the church have been Robert Bergsaker (India), Laura Strand (South Africa), Odd Børresen (Congo), Torborg Larsen (Israel), Solvor and Geir Hande (Niger), Unni and Werner Haugen (Congo), and Heidi and Roberto Enconado (the Philippines).
