Can a Single Ceremony Reflect More Than One Religion?

You can incorporate two religions into your wedding by having an interfaith ceremony. This type of wedding mingles various traditions, thus having no “correct” method. Often, two officiants will preside so that both religions are represented and the appropriate customs can be carried out. In order to avoid any conflict, consider holding your wedding outdoors or in another neutral setting.

For example, a ceremony that combines Jewish and Catholic traditions might be performed by a priest and a rabbi and include the following:
An Opening Statement by Rabbi and Priest -- the two religious leaders welcome the guests and declare the bride and groom's desire to celebrate the faiths of their families and the roots of their shared religious beliefs.
Readings -- from both faiths, probably from the Torah and Old or New Testament.
The Vows -- may be led by either religious leader, but which might most meaningfully be led by the priest, since the declaration of vows signifies the moment that a bride and groom are officially wed in the Christian tradition.
The Blessing and Exchange of Rings -- may be led by either religious leader, but which might most meaningfully be led by the rabbi, since it's the bride's acceptance of the groom's ring that officially weds the couples in the Jewish tradition.
The Seven Wedding Blessings -- in which the rabbi recites the traditional blessings, or Sheva Berachot. For each blessing, the rabbi might first say them in Hebrew, then in English.
Sign of Peace -- in which the priest prompts the congregation to exchange gestures of friendship and peace and leads them in prayer.
The Final Prayers -- in which the bride and groom take turns reciting the Sh'ma and the Lord's Prayer.
The Breaking of the Glass -- in which the Rabbi prompts the groom in the traditional breaking of the glass.
