DH and I had an intimate (8 person) civil wedding August 2011 after my father was diagnosed with cancer. It was important to me to have my father present at my wedding. I was a practicing Catholic, DH was baptized but not confirmed. He is going through the confirmation process currently, and as we embark on growing our family, we have decided that it is time to have our marriage validated by the church.
In the eyes of the Church, this will be our wedding day, and as such we have decided we want to celebrate our sacramental marriage. We are hoping for a late 2013 convalidation (november/december). I do plan to wear a full wedding dress, and DH will be wearing a Tux. There will be a small wedding party (3 on each side) comprised of our siblings and our two best friends.
We have a guest list of approximately 50- family and a few close friends only. We will be hosting a dinner after the ceremony for those who attend, but there will most likely be no DJ/bouqet toss/reception type things.
I'm struggling with two things
A) Do we need to send Save the Dates to family and friends? Those who come to witness the ceremony will be traveling 4-6 hours.

I'm *really* struggling with how to word our invitations. Our family all know that we are were married (in a civil ceremony) and many of DH's family members are not Catholic. I'm not sure how to express that this is an important step in our joureny as a married couple for those who are not familiar with our faith.
Any advice would be appreciated.
