I think the Orthodox would be a little amused, and probably some other things too besides “amused”, to know that the Roman Church is making judgments as to whether their sacraments are valid or invalid.
Well, the way I read the situation, the Catholic Church
is “making a judgment” on whether a sacrament, i.e., a particular marriage between a Roman Catholic and an Orthodox Christian, is objectively valid. The Orthodox Church believes herself to be the One True Church, and if anything, is more assertive and more absolutist about this, than the Catholic Church is. They have always come across to me, as viewing other non-Orthodox Christians with a sort of deigning condescension, to the effect of “the Holy Spirit
may be in your Church and in your sacraments, but we really can’t say, because we can only say where grace
is, not where it is
not, and all we know for a fact, is that grace exists in the one true Orthodox Church.” It comes across sounding kind of like “bless your hearts, you just don’t realize that you have to become Orthodox”, or sort of how we view Anglican sacraments — superficially, the right words are there, the right ceremonies, but at the end of the day, they’re just invalid.
