Very true. Just being married outside of the church is enough to cut you off from the sacrament. Example: If a catholic man marries a protestant woman in a protestant church without permission from a catholic priest, he should be denied the Eucharist in a catholic church.
I’m married outside the Catholic Church. It would never occur to me to take the Eucharist. I assume I can go into the confessional, though, to be absolved and to promise to marry properly.
However, I do know that if a Catholic wishes to marry a nn-Catholic Christian, he can obtain a dispensation for the marriage. If they wish to be married in front of a non-Catholic minister, they also need a dispensation. I don't think it's ordinarily hard or time-consuming to get such a dispensation.
But if the Catholic doesn't bother getting a dispensation, it's taken as a rejection of the Catholic sacrament and is rather more serious, akin to a rejection of the Church. And in this case,the marriage would not be considered valid for that reason
This can be remedied, I think, by Confession and also having the marriage re-witnessed in the Church.
Am I correct here?
