That’s a contract between the Vatican and the swiss guard, not a formal statement about vaccine mandates binding the faithful.
There’s an important distinction the swiss guard or its members are right to fight over.
There is no contract with Vatican employees nor Vatican visitors.
Bergoglio is too chicken to make a formal statement on any moral matters.
There is no formal statement that adulterers may receive Holy Communion but it’s obvious with Bergoglio’s heretical Amoris Laetitia.
The article never claimed there was a “formal statement”.
But Bergoglio’s actions speak louder than any “words” he may or may not say.
