The Pope has reached the two-week mark in his recovery from pneumonia, as doctors suggested he had overcome the most critical phase of the infection – while not declaring him out of danger entirely.

The Vatican’s update on Friday morning also suggested a level of normalcy and routine as the 88-year-old continues recovering at Rome’s Gemelli Hospital.

“As in past days, the night was tranquil and the pope now is resting,” the Vatican said.

In their Thursday evening bulletin, doctors said Francis’ clinical condition had confirmed that he was improving.

Additionally, Francis left his hospital room to go to his nearby private chapel to pray, while continuing with respiratory physiotherapy and work, the Vatican said.

For the second day in a row, doctors avoided saying Francis was in a critical condition, suggesting he had overcome the most acute phase of the infection.

But given the complexity of his lung infection, they said “further days of clinical stability are needed” before they revise their prognosis officially and say he is out of danger.

Francis has been at Gemelli Hospital since February 14 after his bronchitis worsened.

He has shown steady, albeit slight improvements since a respiratory crisis and kidney trouble over the weekend sparked fears for his life. The improvements beat back speculation of an imminent death, resignation or a conclave and signalled that he is still very much in charge.

Prayers continue to pour in from around the world for the Pope.

Despite his improvements, Francis’ near-term upcoming calendar of events is being changed. The Vatican cancelled a Holy Year audience scheduled for Saturday, and it remains to be seen if Francis would miss his Sunday noon blessing for the third week in a row.

Ash Wednesday next week starts the Lenten season leading up to Holy Week and Easter, which this year falls on April 20.

In past years, when Francis has battled bronchitis and influenza in winter, he curbed his participation in Ash Wednesday and Holy Week events, which call for the pope to be outdoors in the cold leading services, participating in processions and presiding over prayers in the solemn period in which the faithful commemorate Christ’s crucifixion and resurrection.

Beyond that, Francis has a few major events coming up that he presumably would hope to keep if well enough. On April 27, he is due to canonize Carlo Acutis, considered to be the first millennial and digital-era saint.

The Vatican considers the Italian teenager, who died of leukaemia in 2006 at the age of 15, an inspiration for young Catholics.

Another important appointment is the May 24 commemoration of the 1,700th anniversary of the Council of Nicea, Christianity’s first ecumenical council.

The spiritual leader of the world’s Orthodox Christians, Patriarch Bartholomew I, has invited Francis to join him in Iznik, Turkey, to commemorate the anniversary, which he has called an important sign of reconciliation between the Catholic and Orthodox churches.

Before he became ill, Francis said he hoped to go, though the Vatican has not confirmed the trip.
