I can appreciate that. In the ME, it is not uncommon for an Eastern Rite Catholic to marry someone from an Orthodox Church. They handle this in various ways. For example, in my parish, the women attend the church of the husband. As such, when major holidays like Christmas and Easter arrive, we often find Orthodox spouses attending our services on those feast days and vv. It all works out in the end.
Yes. I wish we could do away with these divisions. I don’t think that they are helpful. There are histories behind the differences, but as you said, it all works out in the end.
