” In an effort to block posthumous rebaptisms by the Church of Jesus Christ of Latter-day Saints”

Why would they worry about it?

[colorcountry]

Perhaps because they view the “rebaptism” of their dead, by a group they don’t consider Christian to be sacreligious and disrespectful.

I wouldn’t like it, would you?

[ArrogantBustard]

Giving LDS the records (knowing that the LDS will then use them for "posthumous baptisms") might be seen as recognising the legitimacy said "posthumous baptisms". In fact, the Church considers any LDS "baptism" to be invalid, spurious, null-and-void, utterly without effect ...

[livius]

I think it’s mostly that it inflates the Mormons’ statistics. Obviously, no dead person can be baptized by anybody of any church, and such “baptism” would have no effect. But then that person is counted as a Mormon (by the Mormons, of course).

1 Corinthians 15:29
"Else what shall they do which are baptized for the dead, if the dead rise not at all? why are they then baptized for the dead?"

“Why would they worry about it?”

Makes no sense to oppose it.

You would think Catholics would be happy to have us Mormons spend our time and resources building, maintaining and attending temples that they think accomplish nothing. If we didn’t do that, we would have a more available to put into missionary work for the living.

By LDS doctrine, the person the baptism is done for has to want it to be done for it to have any validity, so opposing it is like saying a) the Mormons have the authority to do this and b) those they are done for will be happy for the chance to leave the Catholic church.
