The Catholic Church in America, also called the Roman Catholic Church, or the Church of Rome, follows strict doctrinal traditions, including those pertaining to the marriage ceremony. Although adherence to these traditions may vary slightly according to each individual parish priest's interpretation, there is usually very little deviation from tradition. This is especially true when the vows are recited during a wedding mass. Here are two examples of generally acceptable vow phrasings:

    "I, ________________ , take you, ________________, for my lawful wife/husband, to have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and health, until death do us part."

    or:

    "I, _______________, take you, _________________, to be my husband / wife. I promise to be true to you in good times and in bad, in sickness and in health. I will love and honor you all the days of my life."
    Eastern Orthodox    
       
    The churches of the Eastern Rite (including Greek and Russian Orthodox) are similar in some ways to the Catholic Church. The marriage itself is a long ceremony rich with symbolism. An Orthodox wedding begins with a betrothal ritual that includes the Blessing and Exchange of Rings. The rings are exchanged between bride and groom three times to signify the Holy Trinity. At the close of this betrothal ritual, there is the Marriage Rite, including the Candles and the Joining of Hands, followed by the Crowning, the Cup and, finally, the Triumphal Procession of Isaiah. The vows themselves are spoken silently during this service, but the couple is considered married when the crowns are finally removed by the priest and he blesses them by saying:

   
    "Be thou magnified, O bridegroom."
