I read more about Laestadianism. It sounds very sectarian and exclusivist (only they have the true faith). How can they exist in the same church?
I apologize the delay. I didn't want to give you a flyby reply so I took time to consult people more learned than myself.
We exist in the same church because, at the end of the day, we don't disagree on the only thing that matters -- what we believe: faith alone, the Bible, our sacraments. Everything else is adiaphora: to use or not use birth control, watch TV, trousers/skirts, those are lifestyle choices and we go by the Romans 14. Let each one eat, drink, or refrain, as long as they are
fully convinced in their own mind they do it in honor of our Lord.
The Laestadians
want to stay in the Evangelical Lutheran Church; they are pro-God-installed authority and have a very strict ban against not quitting the Church. From time to time, the bishops sit down with their layman leaders to gauge whether we are still on the same page and whether the Laestadians share the tenets of the church. So far, the bishops have concluded that yes, they indeed do. There is no reason to believe that this would change since the Evangelical Lutheran Church of Finland is not going to ditch its 500-year-old Lutheran doctrines and the conservative Laestadians are no more likely to do that.
As a rule, the thicker the rule book, the more likely the (religious) group is to get at loggerheads over the interpretation of their rule book and split, and split, and split into smaller groups. The Finnish Conservative Laestadians are no exception. According to Wikipedia, there are väyrysläisyys, pellikkalaisuus, kvaenangenilaisuus, alatalolaisuus, erikiaanit, lundbergilaiset, vanhalalaisuus, hölläläisyys, kinnulalaiset, gröndahlilaisuus (all named after their leader), etc., etc. you get the picture and this just before 1930... Anyway, this tendency for every man to form their own visionary group of Laestadian (named after Lars Levi Laestadius) pietism, may partly explain the Laestadian ban on quitting the "mother church," the ultimate umbrella and glue.
Some Laestadian splinter groups have left the Church over the decades but they are a very, very tiny minority, some few hundred people in total. While the most extremist Conservative Laestadian "the only ones to have true faith" groups probably exists in our Church mindful that the Sacrament of the Altar remains valid even if a wicked "no true faith" priest administered it, most of the Laestadians lead their parish life side by side with us who only have 2.3 children per family.

As I mentioned, one of our pastors is a Laestadian. I'm 100% certain that when he goes to baptize a child, the young family will have no idea and no clue of his background and why should they? When it comes to his personal life and family, no doubt he does lead a more (religiously) disciplined life than I do, then again, not unlike my disciplined sportswoman's healthy lifestyle (for my God-given own & only body), if you get my drift. We both do it to honor our Lord. Our Archbishop's former adviser on (no less than) theology was a Laestadian. He was then elected as a vicar of a southwestern semi-urban parish outside the Laestadian heartland. Could be future Archbishop candidate. Just to give you an example how even the Conservative Laestadians
are part & parcel of our church.
