Marriage vows

Marriage vows are promises a couple makes to each other during a wedding ceremony.

Civil ceremonies often allow couple's to choose their own vows, although many civil marriage vows are adapted from the traditional Catholic wedding vow "To have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness or in health, to love and to cherish 'till death do us part."

Vows can also be written by the couple, or poetry, lyrics or vows from a mixture of religious traditions used. However couples marrying in a house of worship or within a religious tradition are often constrained to use the standard vows of that tradition's ceremony.
