But the country is now a full grown Christian country. But Christianity was not introduced in Iceland in one day. It followed a gradual introduction and advent in the history of Iceland religion.
Iceland religion at the present day Iceland is full of the Lutherans. But there are other religion and religious sects as well.
Some of these are, Catholics, Jehovah's Witness, Mormons, Muslims and some other not-so-popular religious sects.
In 1000 C. Iceland became a Christian nation to satisfy some official purposes. But paganism was in vogue at that time also. Later it fully became a Christian country.
Catholics were there at the initial period of Christianity. But after the 'Reformation' catholicism was almost obliterated from Iceland and the Lutherans prevailed.
Today's Iceland has taken more a secular stand though there are strong religious influences in some part of Iceland life.
