sentences:  The grounds for the Korpela movement were laid in 1928 when Toivo Korpela, a self-proclaimed Laestadian preacher who had been rejected from his congregation in western Finland, started to travel around the Torne Valley to preach.The mainstream of the Laestadian movement were troubled by his activities and in 1931, it was openly suggested that Korpela could have "succumbed to vice" and that "the authority of the word of god was endangered" unless he changed his view on important matters of faith.When Korpela stopped preaching in 1934 due to his conflicting views with the Swedish Laestadian church, the movement survived without his leadership and new leaders emerged from inside the community.
