I hope this can be resolved so that researchers won't suffer. I doubt that the pope believes that a dead Catholic will be adversely affected because a fifth cousin three times removed had some kind of proxy baptism performed for him in the Mormon church 100 years after his death.
This is an invasion of personal privacy.
Genealogical research? What does that accomplish? We are all descended from Adam and Eve and that is their point in gathering these documents. They require that all converts to the mormon faith document their genealogy in order to have their ancestors baptized. in the process, they have discovered that after 10 generations one can trace their ancestry all the way back to the first two humans.
What I think is being prohibited is parishes materially assisting LDS heresy by providing records directly to them.
And I'm a genealogical researcher, AND I've used the LDS records.
By the way, they are not all that accurate, as they are submitted by all sorts of people of varying expertise -- some of them are worse than the little old ladies in tennis shoes who keep trying to find some family descent from Bonnie Prince Charlie (vide Florence King's Southern Ladies and Gentlemen). There are some awful errors in the LDS databases. I don't enter anything in my database proper unless I have verified it directly by seeing the actual records - otherwise it stays in my working notes.
