I can tell you exactly what my husband and I said during our civil ceremony because it was only 11 months ago and I have kept the booklet with the ceremony written out in full in. The word vow isn't necessarily a religious term, it just really means solemn promise, its just the church uses it but then they use a lot of words.
Oh and we weren't allowed to have any readings or music that had any religious connotations.
Ok...so I will try and just put in the bits that you might be interested.
......... and ......... today you will exchange vows of marriage which will unite you as husband and wife. These vows are are a promise of lifelong commitment, giving your families and friends the opportunity to meet together in celebration of your happiness and to impart their own message of love and support.
blah blah
Marriage is the promise of hope between two people who love each other, who honour one another as individuals and who wish to share their future together. It enables people to share their dreams and memories, their joys and laughter and to help each other through troubled times. It encourages them to risk more and thus to gain more.
blah blah
then you do the I know not of any lawful impediment business and then the ''I do'' bit.
Then for the formal vows of marriage we had a choice of 3
A).........I give you this ring as a symbol of our marriage and as a lasting reminder of the promise we have made her today.
B)........I give you this ring as a symbol of our marriage, I promise to give you my love and friendship, I promise to confide in you, to trust and protect you, I promise to be there when you need me most, always and forever.
C)........I give you this ring as a symbol of my love, all that I am I give to you, all that I have I share with you, I promise to love, cherish and protect you for as long as we both shall live.
