So, the marriage is more important than God? I did the very same thing, married a Methodist in my parish church without a Mass. It was apparently a huge mistake. I wish I had waited and insisted on a Catholic.
A Mass is in two parts. The Liturgy of the word that all may participate in and the Liturgy of the Eucharist which is only for those who are Catholic.
Out of the clear blue, I met my husband and it seemed right. He was the one I was supposed to be with. He was older than me and had never married either.
I took it to the Adoration Chapel, I spoke at length to a priest I explicitly trusted. Then I took the leap of faith. Seven years and we are good. I left it up to God that I was reading the situation the right way. I know many people get married for all kinds of reasons. I was older so I thought about it maybe more than young people do.
