From the Book of Common Prayer:
Dearly beloved: We have come together in the presence of
God to witness and bless the joining together of this man and this woman in Holy Matrimony. The bond and covenant of
marriage was established by God in creation, and our Lord
Jesus Christ adorned this manner of life by his presence and
first miracle at a wedding in Cana of Galilee. It signifies to us the mystery of the union between Christ and his Church, and Holy Scripture commends it to be honored among all people.
The union of husband and wife in heart, body, and mind is
intended by God for their mutual joy; for the help and comfort given one another in prosperity and adversity; and, when it is God’s will, for the procreation of children and their nurture in the knowledge and love of the Lord. Therefore marriage is not to be entered into unadvisedly or lightly, but reverently, deliberately, and in accordance with the purposes for which it
was instituted by God.
The Book of Common Prayer was dumped by the Episcopal Church in 1979. At the same time it also dumped the Articles of Religion which were part of the Prayer Book and were the fundamental precepts of Anglicanism (sort of like the Westminster Confession was/is for Presbyterians).
One reason they dumped the Articles was that the Articles stated that it was not lawful for the Church to promulgate any teaching contrary to Holy Scripture, and that no member could be forced to adhere to such false teaching. Of course, that went by the wayside a long time ago.
