The worst part about this is the deliberate scandal: the two leading vaccines (Pfizer and Moderna) do not use cell lines drawn from aborted fetuses. In essence, they are answering a question that wasn’t necessary, for the same reason they create absurd nativity scenes: because they take delight in scandalizing faithful Catholics.
The actions of disobedience to Christ, brazen apostasy, scandal and sheer delight in evil is accelerating. They probably believe that they have won or that ever more extreme scandal is needed to pry the remaining Catholics from the Barque of Peter.
Don’t let yourself be scandalized. These people are no more Catholic than Buddha.
