The lighting of a unity candle isn't based in any particular faith, but the practice has become more and more common in modern wedding ceremonies. It's not hard to see why – the beauty of two flames coming together as one can be incredibly poignant. If you're considering including the tradition in your upcoming nuptials, be sure you understand the history, function and procedures associated with unity candle ceremonies. How does the unity candle work? The unity candle is lit by the bride and groom from two separate family candles, representing the union of your families and the fact that you and your fiance are creating a family of your own. Often your mothers light the family candles, and then you two each hold your family's candle to light the unity candle together. But your dads can be in on it, too -- a nice option, because it mirrors the commitment you two are making and reminds everyone present of your parents' commitments. When is the Unity Candle Lit? Usually the unity candle is lit directly after you exchange vows. Can the two sets of parents light it, and then the bride and groom use it to light theirs? Unity candle traditions are flexible, giving couples the freedom to customize the experience for their special days. If it is important to you for both sets of parents to be involved in the wedding unity candle ceremony, by all means, include everyone. Where Does the Wedding Unity Candle Tradition Come From? Unity candle ceremonies are a relatively new trend. The use of a unity candle in weddings only became popular in the last few decades. The exact origins are unknown, but the use of a unity candle in a 1981 "General Hospital" episode may help explain the initial popularity of the trend. Symbolically, flames are said to represent the love and passion each partner has for the other. Joining them together is a physical representation of the couple's enduring commitment.
