Pope Francis began noninvasive ventilation on Friday after experiencing a respiratory crisis that led to a “sudden worsening” of his condition, the Vatican said.

Pope Francis on Friday urged liturgists to accompany bishops and the faithful communities of their dioceses with humility and discretion.

The Vatican advises against publishing damaging accusations without valid reasons, especially if the accused is deceased and cannot defend their name.

Pope Francis’ clinical condition remains stable after Friday’s bronchospasm episode that caused vomiting and sudden respiratory deterioration, according to a Holy See Press Office statement released Saturday evening.

Pope Francis showed more signs of recovery on Thursday, but more time is needed to determine his medical prognosis.
