This sounds like the Catholic bashing that went on as to JFK back in the day. The author does not cite to any opinion Judge Barrett has joined in the 7th Circuit he claims was wrongly decided because of her faith.
The first Catholic Chief Justice gave us Dred Scott.
For one thing, Zmirak is a very knowledgeable, and very politically active, orthodox Catholic who --- note this ---- vehemently agrees with most of Amy Coney Barret's moral principles.
He does not raise question marks about this judge because she is Catholic, NOR because she has Catholic principles, but because --- unlike the excellent Scalia and Thomas --- she wrote an essay 10 years ago in which she doesn't seem to navigate the difference between "moralist" and "jurist" very well.
It would be worth discussing the essay in question, rather than to try to slap down John Zmirak, of all people, as --- this is ludicrous --- an anti-Catholic.
