There is no counter accusation (in fact I left Sonia Sotomayor off the list which could theoretically serve that purpose), nor did I raise a different issue to avoid the difficult question. So nope!
Instead I pointed out that four GOP nominated justices are already Catholics and asked if that was a big deal during their confirmations. (I don't know if the answer is no for any of them, or if all of them faced such questions, or somewhere in between). Since, assuming that Barrett is confirmed six out of nine justices would be Catholic I think it is difficult to argue that being Catholic is by itself a problem. But Barrett isn't just a Catholic.
Now based on
their website and
FAQ I am not sure that the "public facing" "People of Praise" is an issue either (beyond admiring communists of course - "The People of Praise is a charismatic Christian community. We admire the first Christians who were led by the Holy Spirit to form a community. Those early believers put their lives and their possessions in common, and 'there were no needy persons among them'.") But the headlines talk about the "secretive" nature of the group and I think it is appropriate to make certain that the "public facing" aspects are accurate and specifically what this "Our covenant is neither an oath nor a vow, but it is an important personal commitment" means to Barrett. But these seem to be easily answered just by rephrasing the next sentence " We say that People of Praise members should always follow their consciences, as formed by the light of reason, and by the experience and the teachings of their churches" to minimize that last little bit.
For full disclosure if I was president I would not be nominating any Catholics anytime soon. Not because there is something wrong with being Catholic (half my family is Catholic) but because I think it would be healthy to have some religious diversity on the court the same way others want diversity in education among other things. But that would also be why I would not want here mainstream religious beliefs to be much of a topic because we all know they will be used as "whataboutism" if an atheist or muslin or hindu was nominated as justification.
