They didn’t state that it was invalid I just meant that it wasn’t physically in her church.
Cool. That’s a common misunderstanding in the Catholic context, too. When folks talk about people being married “in the Catholic Church”, it’s often misinterpreted as “in a Catholic building.” (It doesn’t mean that – it’s possible to get a dispensation from form and be validly married “in the Catholic Church”, even when the ceremony isn’t “in a Catholic building.”)
Still, it makes even less sense that a canonist would say “since ya’ll weren’t married
in a Protestant building, your marriage isn’t valid.” I’m guessing that – since you mentioned this in the context of what they told you, right? – therefore they mean that, for whatever reason, it wasn’t considered valid by her ecclesial community.
From the way you report it, you sounds like bridges have been burned, but it would be interesting to know, specifically,
why it is considered invalid. If you feel that you are able to engage your deacon, that would be the question – “I understand that you’re saying that the wedding resulted in an invalid marriage, but I don’t understand
why it’s invalid; everything I’ve read seems to suggest that it
should have been considered valid. What am I missing, here?”
