How do I word the invitations for a vow renewal ceremony?
This type of ceremony is commonly referred to as either a reaffirmation or a renewal of vows. The invitation could read something like:
The honor of your presence
is requested at the reaffirmation
of the wedding vows of
Mr. and Mrs. Jerry Orrell
Sunday, the third of March
at three oclock
St. Marys Church
Indianapolis, Indiana
and at a reception following
in the basement of the Church
