My late parents did the same thing. My dad was in the AirForce, when he was sent to the University of Buffalo and worked the ROTC program. While in Buffalo, he met my mother by chance one day while in the bookstore owned by some friends, who my mother also just happend to know.
They got married by a justice of the peace in a town near Buffalo in 1955,forgot the exact date, and I was born,June 9,1956.
Later on, my dad who was a master sargenant, got sent to KellyAFB here in San Antonio
where he worked in military intelligence at Security Service.
Then sometime after momma and daddy had lived here awhile, they were married with some friends as witnesses in the National Shrine of the Little Flower down on Kentucky St. by Father Hilary Smith,O.C.D. I have a copy of this.
Elts1956, similar thing with my dad’s parents. I have their marriage license from Milwaukee from 1915.Now, grandpa was a Catholic and grandma was Lutheran,but she agreed to raise any children(my dad and Uncle Tom) as catholics.She also converted later on.Did they have a church wedding, don’t know.Never thought to ask my dad that one.
To me, I never have worried about whether my parents were considered living in sin by the church before they were married in Her. It’s not important to me, with all the wars and killing,and abused children and other things out there, this is trival stuff.
I try to contribute money to various organizations run by Holy Mother Church to help those in need and even groups like Doctors without Borders,becuase I work two jobs and it is hard for me to volunteer. But when and if I get all my debts paid off,and can finally retire, I plan to volunteer, especially working to be a child advocate or help prevent elder abuse.
Enjoy your parents while you have them with you.Mine are buried down at Fort Sam Houston National Cemetery, and I try to see them whenever I can.Took my dad a plant for Father’s Day.
Whatever happend in those 12 months before they got married in the Church is between them and Jesus, and He is most merciful and forgiving.So don’t worry about this business with your parents.
