anthropologist: When Same-Sex Marriage Was a Christian Rite
Contrary to myth, Christianity's concept of marriage has not been set in stone since the days of Christ, but has constantly evolved as a concept and ritual.
Prof. John Boswell, the late Chairman of Yale University’s history department, discovered that in addition to heterosexual marriage ceremonies in ancient Christian church liturgical documents, there were also ceremonies called the "Office of Same-Sex Union" (10th and 11th century), and the "Order for Uniting Two Men" (11th and 12th century).
These church rites had all the symbols of a heterosexual marriage: the whole community gathered in a church, a blessing of the couple before the altar was conducted with their right hands joined, holy vows were exchanged, a priest officiatied in the taking of the Eucharist and a wedding feast for the guests was celebrated afterwards. These elements all appear in contemporary illustrations of the holy union of the Byzantine Warrior-Emperor, Basil the First (867-886 CE) and his companion John.
Such same gender Christian sanctified unions also took place in Ireland in the late 12thand/ early 13th century, as the chronicler Gerald of Wales (‘Geraldus Cambrensis’) recorded.
Same-sex unions in pre-modern Europe list in great detail some same gender ceremonies found in ancient church liturgical documents. One Greek 13th century rite, "Order for Solemn Same-Sex Union", invoked St. Serge and St. Bacchus, and called on God to "vouchsafe unto these, Thy servants [N and N], the grace to love one another and to abide without hate and not be the cause of scandal all the days of their lives, with the help of the Holy Mother of God, and all Thy saints". The ceremony concludes: "And they shall kiss the Holy Gospel and each other, and it shall be concluded".
