Certainly. But here I mean that the flow probably came through the Norse. The Scotts definitely got their term from the Norse. Since "Christianity gained a foothold in Finland during the 11th century. It was strengthened with growing Swedish influence in the 12th century and the Finnish "crusade" of Birger Jarl in the 13th century." [Wikipedia] and since the Swedes were often trading and plundering along the Finnish coast, then I strongly suspect that the current Finnish word came from the Swedish one, which comes from the same Germanic root as in English.

The only etymology I could find is: kirkko [from Germanic. Compare Estonian kirik, Karelian kirikkö, Lapland girku, Swedish kyrka] : church

A quick scan of http://www.freeweb.hu/etymological/finnish.htm shows many words of Germanic origin. I like how "kihlat" (dowry) compares to the Swedish "gisslan" (hostage).
