One can not add or subtract from the Bible.
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.
