So, from the point of view of the Russian language, as well as legal, civil marriage should be called a relationship between a man and a woman, officially registered in the registry office without the participation of the church. Spouses, unlike boyfriends, get not only a new status, but also the special rights and duties that may be settled by the law, as well as the marriage contract.
Apparent contradictions in the interpretation of the term attributed primarily to the fact that nowadays civil marriage became the only form of officially registered relationship between a man and a woman, as the sacraments are no longer valid from the point of view of jurisprudence. The terms "civil marriage" and a "marriage" have become synonymous, and the people have given one of them a new value.
In pre-revolutionary Russia, the controversial term now opposed the concept of "church" as a non-sectarian institution of marriage in those days was absent. When the state was separated from the church, it arrogated to itself the right to regulate and legalize the relationship between lovers, so that civil marriage is completely supplanted religious.
