Traditionally, there are three candles. The mothers each light one of the side candles.
The bride and groom then each take one of the side candles and together they light the center candle. They may then blow out their individual side candles to symbolize the extinguishing of their two single lives. Or, as is more common today, they may keep those candles burning to symbolize that their individualness is not extinguished, even though they are united in marriage.

Sample Wording for Unity Ceremony:

"____ and ____ are going to light their wedding/unity candle, as a symbol of their marriage. The candles from which they light it represent each of them in the fullness of their personhood. They come into their marriage relationship as individuals and they do not lose their identity, rather they create through their commitment the relationship of marriage. Therefore, three candles remain lighted, one for each of them and one for their marriage as symbols of their commitment to each other and to a lasting and loving marriage."

"The two outside candles have been lighted by their parents to represent their lives to this moment. The lights, representing the faith, wisdom, and love they have received from their parents, are distinct, each burning alone. They light the center candle to symbolize the union of their lives. As this one light burns undivided, so shall their love be one with God. From now on their thoughts shall be for each other rather than for their individual selves. Their joys and sorrows shall be shared alike. Holding hands, they encircle the alter and candle to symbolize the sacrificial nature of their life journey together. May the radiance of this one light and their jouney together be a testimony or their unity."

"The two outside candles of the candelabra have been lighted to represent their lives to this moment. They are two distinct lights, each capable of going their separate ways. To bring bliss and happiness to their home there must be the merging of these two lights into one light. This is what God meant when He said: 'On this account, a man shall leave his father and mother and be joined to his wife and the two shall be one flesh.' From now on their thoughts shall be for each other rather than for their individual selves. Their plans shall be mutual, their joys and sorrows shall be shared alike. As they each take a candle and together light the center candle, they will extinguish their own candles, thus letting the center candle symbolize the union of our lives into one flesh. As this one light cannot be divided, neither shall their lives be divided. May the radiance of this one light be a witness of their unity in Christ."

[This one is for a ceremony that uses a unity candle with the cross and double rings design on it.] "On this their Wedding Day, they make this loving commitment, to follow the greatest Commandment of all: 'Love one another, as I have loved you.' This they do in the hope that their union shall become a symbol of God's promise to merge two devoted lives into one. The two distinct flames represent their lives to this moment; individual and unique. To bring bliss and happiness to their home there must be the merging of these two into one. Together they light the center candle. This is what God meant when He said: 'On this account a man shall leave his father and mother and be joined to his wife and the two shall become one.' From now on their thoughts shall be for each other rather than for their individual selves. The entwining rings -- symbolize their two lives joined in dependence and growing maturity. Their plans shall be mutual, their joys and sorrows shall be shared alike. The cross -- a constant reminder of their faith in the Lord who blesses us each day, for it is He who enriches their marriage in every possible way. Thus rhey extinguish the two, forever united in the radiant oneness of God's love. Let them renew their vows each day as the memory of this joyous occassion reminds us:

The Way is Long -- Let Us Go Together
The Way is Difficult -- Let Us Help Each Other
The Way is Joyful -- Let Us Share It
The Way Is Ours Alone -- Let Us Go In Love
The Way Grows Before Us -- Let Us Begin"

"Together they light one candle from two smaller candles as they acknowlege their union as husband and wife. By allowing the flame of the two smaller candles to remain lit, they also accept the individuality of each other as a means to fulfilling their oneness."
[Between the Greeting and the Opening Prayer:] "On the day of their baptism, God began in (groom's name) and (bride's name) the process of becoming a Christian. They were given the privilege of being a light, an example to the people they would meet. Their process of becoming a Christian continues today. A new dimension is added as they celebrate the Sacrament of Matrimony. Today they come here from two different families. Out of these two families, a new family will be created in the Lord. At this time, I would invite the parents of (groom's name) and (bride's name) to come forward and light the individual candles which represent the two separate families who present son and daughter to the Lord in the Sacrament of Matrimony. The two individual flames, one representing each family, will demonstrate to us in a very beautiful way the symbol of two who become one." ... [Between the Blessing and Exchange of Rings and the Prayer of the Faithful:] "One in the Lord -- they symbolize this fact by lighting a third candle from their individual ones. From now on they will grow together as unique persons becoming another Christ, a light to the world."

"From every human being there rises a light that reaches straight to heaven. And when two souls are destined for each other and find each other, their streams of light flow together and a single brighter light goes forth from their united being." (by Baal Shem Tov)

"Your gift to each other for your wedding today has been your wedding rings - which shall always be an outward demonstration of your vows of love and respect; and a public showing of your commitment to each other.

You now have what remains the most honorable title which may exist between a man and a woman - the title of "husband" and "wife." For your first gift as husband and wife, that gift will be a single rose.

In the past, the rose was considered a symbol of love and a single rose always meant only one thing - it meant the words "I love you." So it is appropriate that for your first gift - as husband and wife - that gift would be a single rose.

Please exchange your first gift as husband and wife. In some ways it seems like you have not done anything at all. Just a moment ago you were holding one small rose - and now you are holding one small rose. In some ways, a marriage ceremony is like this. In some ways, tomorrow is going to seem no different than yesterday. But in fact today, just now, you both have given and received one of the most valuable and precious gifts of life - one I hope you always remember - the gift of true and abiding love within the devotion of marriage.

_________ and _____________, I would ask that where ever you make your home in the future - whether it be a large and elegant home - or a small and graceful one - that you both pick one very special location for roses; so that on each anniversary of this truly wonderful occasion you both may take a rose to that spot both as a recommitment to your marriage - and a recommitment that THIS will be a marriage based upon love.

In every marriage there are times where it is difficult to find the right words. It is easiest to hurt who we most love. It is easiest to be most hurt by who we most love. It might be difficult some time to words to say "I am sorry" or "I forgive you"; "I need you" or "I am hurting". If this should happen, if you simply can not find these words, leave a rose at that spot which both of you have selected - for that rose than says what matters most of all and should overpower all other things and all other words.

That rose says the words: "I still love you." The other should accept this rose for the words which cannot be found, and remember the love and hope that you both share today.

__________ and ________, if there is anything you remember of this marriage ceremony, it is that it was love that brought you here today, it is only love which can make it a glorious union, and it is by love which your marriage shall endure."

_______ and _______, you have just sealed your relationship by the giving and receiving of rings and the exchange of a kiss, and this covenant is a relationship pledge between two people who agree that they will commit themselves to one another throughout their lives. The most beautiful example of this partnership is the marriage relationship. You have committed here today to share the rest of your lives with each other. Today, this relationship is symbolized through the pouring of these two individual containers of sand one, representing you, _______ and all that you were, all that you are, and all that you will ever be, and the other representing you, _______, and all that you were and all that you are, and all that you will ever be. As these two containers of sand are poured into the third container, the individual containers of sand will no longer exist, but will be joined together as one. Just as these grains of sand can never be separated and poured again into the individual containers, so will your marriage be.
