More ignorance - try actually studying the history of the sacrament of marriage.

Liturgical marriage ceremonies date from the 12th century in western Christianity (the Catholic tradition), but there is evidence of church weddings as early as the seventh century in eastern Christianity (the Orthodox tradition). Before the development of these sacramental rites, betrothals and weddings were primarily family celebrations presided over by the parents who arranged the marriages. In the past, both the relationship between the spouses and the ceremony that united them were also called matrimony, derived from matrimonia, the Latin word for marriage.
