This pious jargon sounds, feels and tastes like fraud

The sentence below appears on a religious website.

Each time we go to Mass we must go prepared to have our souls pierced.

Is this not silly nonsense? Who in our society talks about having their hearts pierced?

People get their ears and noses pierced, tongues too. Teenagers draw graphics of arrows piercing hearts. This sort of nonsensical talk really seems like fraud. Annoying too. Is it not simply pious jargon?
