From the June 15, 1952 Watchtower, page 362:
ESTABLISHED
PROCEDURE TO BE FOLLOWED AT WEDDINGAt the time appointed, the persons to be married, having been qualified according to the law of the state and the standards of the Lord, should assemble together, facing the minister; the man at the minister’s left hand and the woman at his right hand. A friendly and intimate appropriate speech is given, directed primarily to the two to be married, outlining the proper Scriptural obligations each one assumes toward the other and toward their God in accepting the responsibility of wedlock. Material such as that contained in the first 19 paragraphs of this article is appropriate. After this, the bride, the bridegroom and the two witnesses should stand together before the minister.
The minister will then say to the man, using his Christian or given name:
"Do you, ________, in the presence of Jehovah God and these witnesses, take ________ to be your wedded wife, to love and to cherish, in accordance with the divine law as outlined in the Holy Scriptures for Christian husbands, for as long as you both may live?"
The man should then answer: "I do."
The minister will then say to the woman, using her Christian name:
"Do you, ________, in the presence of Jehovah God and these witnesses, take ________ to be your wedded husband, to love and to cherish and deeply respect, in accordance with the divine law as outlined in the Holy Scriptures for Christian wives for as long as you both may live?"
The woman should answer: "I do."
[If arrangements are to give the woman in marriage by her father or someone else, the minister will say: "Who gives this woman to be married to this man?" The father or whoever gives her in marriage will say: "I do." Then he will withdraw and take his seat in the audience. If no arrangements are made to give the woman in marriage, this can be dispensed with.]
The minister will then ask the man to repeat after him:
"I, ________, take you, ________, to be my wedded wife, to love and to cherish in accordance with the divine law as set forth in the Holy Scriptures for Christian husbands, for as long as we both shall live or until the divine termination of the marital arrangement."
Then the minister will ask the woman to repeat after him:
"I, ________, take you, ________, to be my wedded husband, to love and to cherish and deeply respect, in accordance with the divine law as set forth in the Holy Scriptures for Christian wives, for as long as we both shall live or until the divine termination of the marital arrangement."
If a ring ceremony is desired, at this point the man may place the ring on the third finger of the woman’s left hand. In case of a double ring ceremony, the woman shall place the ring on the third finger of the man’s left hand. If he desires, the minister may remark in connection with this ceremony: "This ring [or rings] is an outward and visible sign signifying unto all the uniting of this man and this woman in the bonds of matrimony."
The minister will then say: "Forasmuch as [man’s name] and [woman’s name] have covenanted before Jehovah God and these witnesses to accept each other in wedlock, I, as an ordained minister and by the authority conferred upon me by the Holy Scriptures and the State (Province) of ________, pronounce that they are husband and wife together. What God has yoked together, let no man put apart."
