In the modern world we have video cameras we can use to record permanent ceremonies.
Guess again. Video cameras have indeed been around for some considerable time in our modern world - only problem is the format and medium for recording has changed just a tad over the time we’ve had them. Sure there’s still a handful of VHS players around (Beta not so much) but that’s not much help if the tape hasn’t survived. DVDs are fast heading in the same direction along with BluRay and I’m not sure anyone even remembers HD DVD!
But the truth seems, to me, that at least until the generations have moved past the crop of adults who were baptized during the widespread “we baptize” fad of a certain time period, I concur with the assessment that a simple conditional sacrament is reasonable and will not remotely prompt psychological breakdown in any rational adult
Realistically this involves a very limited time period affecting a small number of people (of whom only a fraction would be ordained) and is largely confined to certain places and only one Rite. AFIK there have only been two priests whose ordination was affected by this problem, compared with the significantly greater number ordained worldwide. Yet you would have
every ordinand
in every country conditionally baptised (and confirmed). Good luck with that.
That same logic - assuming invalidity based solely on the fact that a sacrament was administered during a particular time period - would also call into question the validity of other sacraments, such as Holy Orders, since we can’t be completely sure the proper formula was used and there were some weird idea floating around for a while.
We presume, shockingly perhaps, that priests (and deacons) will actually do and say what they’re supposed to when administering a sacrament since this is what they in fact do (occasional exceptions aside). This is also why we recognise the validity of (some) baptisms in other Christian denominations - where there’s a set formula and method we expect that it was actually followed (after all that’s sort of the purpose in having it in the first place). Of course that recognition can change if there’s evidence of widespread departure or freewheeling. This isn’t about ecumneical niceities (since after all we don’t recognise other sacraments) it’s just plain common sense.
Sacraments are administered without issue all the time - I did a baptism a couple of weeks ago and I’ve got another scheduled for a couple of week’s time. I use the proper formula; as does every other priest I know. Yes, mistakes and stuff ups happen; every now and again somebody gets a bright idea and goes off on a jolly of their own. Sure it’s messy and has to be cleaned up but it’s dealt with and everyone concerned moves on. The Church has been baptising people for almost 2000 years, largely without issue. There’s no reason why a couple of isolated foul ups should cause anyone to question their faith or their trust in the Church.
