In this article, the phenomenon of inter-confessional marriages and families is studied in the context of Finnish Orthodoxy. The focus is on the wedding services, religious upbringings and participation in Church life from the perspective of inter-confessional marriages/families: How does the ecumenical reality influence them? Sociologically, the family has a central role in relation to beliefs, religious practices and activities. The religious upbringing of most Orthodox children takes place in a family of two Christian traditions. In the lived reality of the Finnish Orthodox population, the co-existence of two traditions (Orthodox and non-Orthodox) in inter-confessional marriages is not always non-problematic. In dialogue with the Lutheran Church, the Orthodox Church of Finland has aimed to promote harmony and mutual respect for the two traditions in inter-confessional families, as well as to fortify the Orthodox identity of its members.
