Most share the same Judeo-Christian and Lutheran heritage and the majority are baptised and confirmed members of the Evangelical Lutheran Church, who marry and bury within the church, go to church conserts and take their kids to their local parish's playschools. Our Christian holidays -- Christmas, Epiphany, Easter, Ascension day, Pentecost, Midsummer, and All Saints' day -- are national public holidays. Religion is taught at schools, parishes organize weekly morning prayers at schools, school semesters end with Christmas church and Summer church services, 80% of our kids go through confirmation training, and so worth. Religion is everywhere. So I think my community is very religious without it realizing it.
Some are openly believers and active members in their local parish life as I am; some keep their faith private and only attend the Mass but are not active in the parish community; a very tiny minority is militant legalistic brimstone Christians; some consider themselves believers but only attend during the big Christian holidays; many are "cultural Christians" who pay their dues and have a positive view of Christianity and the EVL church but do not really think about their personal faith that much; some don't have personal faith but still have a positive view of the EVL church and especially its domestic social diakonia work and foreign church aid, and therefore want to support the church's good work by being members and paying their dues; some are not members and don't really care one way or another; and only a very tiny majority are openly hostile militant atheist on a mission to dismantle the EVL church.
And then we have the bigger community of (non-Lutheran/EVL) believers -- what I liked to call us Believers United

-- with whom we have very friendly and neighbourly working relations: the Orthodox, Catholics, the Muslim and Jewish communities, and the free church Christians. Slightly exaggeratingly, we have a common ground and worry: it's us vs. secularisation.
Except for the two extremeties, the militant Christians and militant atheists, everyone else gets along just fine. The Nordic spirit tends to favor cooperation and consensus-seeking, values that unite us, instead of focusing on the cracks to drive us apart.
