Læstadius

Lars Levi Laestadius, also written Læstadius (1800–1861), was a Swedish Lutheran pastor and revivalist who founded the Laestadian movement, a pietistic revival within Lutheranism that originated in the Nordic north and spread to Finland, Sweden, Norway, and later North America. He is best known for his work among Sámi communities and rural Christians in the 1830s and 1840s, where his preaching emphasized personal conversion, repentance, and a distinctly lived faith.

Laestadius promoted a revivalist approach that sought to apply gospel principles to everyday life. His message stressed inner renewal, a strict moral code, and social reform, including temperance and care for the vulnerable. He advocated a direct, experiential form of faith and encouraged lay participation in preaching and prayer, which contributed to the spread of his movement beyond ordained clergy.

After his death, the Laestadian revival continued to influence religious life across the Nordic region and among Sámi and immigrant communities abroad. The movement diversified into several associations and denominations, often characterized by conservative practices and strong emphasis on personal piety. Today, Laestadianism remains present in northern Europe and in North America through various Laestadian and apostolic Lutheran groups, commonly referred to as Laestadians. The legacy of Laestadius lies in shaping a distinct strand of Lutheran revivalism that emphasized personal faith, moral reform, and community discipline.
