The Catholic church in Sweden has around 116 000 members today and this number is growing. It's mostly immigrants and refugees that contribute to the increase. The Catholic church is a multicultural church.
If you are baptised in the Catholic Church and a permanent Swedish resident you have been registered as a member of the Catholic Diocese of Stockholm.
You may also have become a member by converting or by moving to Sweden from another country and registered for membership. Some people are also registered as members when they are godparent in a Catholic baptism or witnesses at a Catholic wedding.
If you are a member of the Catholic Diocese of Stockholm you are automatically also a member of the universal Catholic church. At the same time; if you leave the Catholic church in Sweden you also leave the universal Catholic church. The Catholic church is a universal community not connected to national borders.
