- The unity candle ceremony isn't traceable to any of the world's other wedding traditions. But the custom is most like "the candlelight blessing," where the candle's flame is a symbol of Christ ("the light of the world").
- When the bride and groom use two small candles to light one bigger candle together, it symbolizes two becoming one. If the couple lights the center candle together and the mothers each light a candle on either side of the large flame, the unity candle symbolizes the coming together of two families.
- If the mothers (or other significant relatives) are involved, care should be taken that both women are allowed to light their candles at the same time. If stepparents are present, it is best to offer them candles, too.
- Use hurricane covers on candles that will be left sitting for any length of time. Be sure to keep tents, tablecloths or anything else that might blow into a candle flame well away from the candles.
- Many brides and grooms keep their unity candles and relight them together on their anniversaries.
