A Finnish Oriental Orthodox Christian

I didn't that such people exist.
I know hardly anything about Oriental Orthodoxy in Finland. I know that there has been Ethiopian OO services in Helsinki's EO parish's chapel and there is some Ethiopian community or parish in Helsinki but I don't think they have any actual church building and their priest lives in Denmark so I don't think they have much services or anything. I don't live in Helsinki but I've heard that many OO christians attend local EO services there. As for the other cities and communes, I haven't heard any other OO communities. I guess there are some OO immigrants at least in larger cities but that's about it.
As of EO church of Finland, here is the
the official website. Two other fairly good sites are
Ortodoksi.net which is sort of overall databank about all Orthodox-related things and
Tsasouna.net in which a Finnish priest has published numerous articles about teaching of the Fathers and the Church.
Here is the Divine Liturgy of St. John Chrysostom in Finnish and in English and in case your friend a Swedish-speaking Finn
here is the liturgy in Swedish. If your friend understands Finnish he/she might find these interesting.
