Typically the wedding vows are said in the middle of the ceremony, after the welcome and before the exchanging of rings. This may change depending on the length of the ceremony and the different elements present in the ceremony.
A simple wedding ceremony begins with the processional and the bridal march, followed by a welcome or introduction from the officiant. This may include some words about the importance of the vows. The wedding vows come next in the ceremony and the rings are exchanged. The officiant then pronounces the couple, which is followed by the customary kiss. The officiant may also make a few closing remarks or a blessing. The ceremony ends with the recessional.
Many couples also choose to add various elements to their wedding depending on family traditions and beliefs. Readings, songs, prayers or other customs are most often done before the exchanging of vows. However, lighting a unity candle is commonly performed after the vows and rings have been exchanged.
