This chapter presents the assumptions of Christian ethics relating to the issue of
promoting the traditional family model. I analyse the doctrine of particular churches
and religious associations, considering both theological issues and the internal law
institutions of various confessional entities. Given that the community of Christian
churches is extremely broad, the scope of research has been narrowed to only a selection
of entities: in light of the number of followers, the considerations mainly cover
the teachings of the Roman Catholic Church; however, I also examine the position of
selected Protestant and Orthodox communities. The internal law of particular churches
and religious associations is characterised by a high level of diversity, and some
of the confessions have structured sets of legal regulations. In the case of the Catholic
Church, the term ‘canon law’ is used to describe internal law, which was systematised
in 1983 as the Code of Canon Law. The internal norms adopted by the individual churches
and religious associations reflect their religious doctrine and constitute their practical
dimension.
