Content:  In the Eastern Orthodox and Oriental Orthodox Churches, the Rite of Betrothal is traditionally performed in the narthex (entranceway) of the church, to indicate the couple's first entrance into the married estate. The priest blesses the couple and gives them lit candles to hold. Then, after a litany, and a prayer at which everyone bows, he places the bride's ring on the ring finger of the groom's right hand, and the groom's ring on the bride's finger. The rings are subsequently exchanged three times, either by the priest or by the best man, after which the priest says a final prayer. Traditionally, the betrothal service takes place at the time the engagement is announced, though in certain localities it may performed immediately before the wedding ceremony itself. The exchange of rings is not a part of the wedding service in the Eastern Churches, but only occurs at the betrothal ceremony. Traditionally, the groom's ring is gold and the bride's ring is silver.
