Married couple sometimes find that a time has come when a renewal of vows seems appropriate. It may be that their wedding was overseas and they now want to involve family and friends in Australia, or they may just want to re-affirm the love that they share, perhaps involving their children as part of this love.
Renewal of vows can take many forms, but it must be understood that this is not a re-marriage, but a reaffirmation of their previous commitment.
Similar to marriage ceremonies, I have prose and poetry that would be appropriate for this occasion, and what you would like to include is limited only by your imagination
