Many years ago, I had fallen away from Church and during this time I met someone I wanted to marry. She was never baptized or brought up in any particular religion. We were married in a Protestant minister at WDW in 1999.
This year I started to renew my interested in the Catholic faith, and wanted to attend mass. Yes, I was very concerned about my marriage was well. I made an appointment to meet with a parish priest, and explained the entire situation. The priest asked me some basic questions about our relationship, and told me that the Church would recognize our marriage and that I could receive communion.
That’s my story. If you have questions, you may want to consult with a parish priest if it will ease your mind.
