It’s 10am on Sunday, and people are already starting to filter through the doors of Harbour Church. Sun streams through the windows – there’s an air of anticipation as congregation members greet each other and catch up on the week just gone. Soon, the room is filling up, the sound of gentle chatter swelling as the throng grows and people take their seats. The five-piece worship band strikes up; the crowd gets to its feet; the air vibrates as more than a hundred voices sing praises to God.

Is Christianity back? Across several countries, the last few months have seen numerous anecdotal reports of a resurgence of Christian observance. Many British clerics are noting strong attendances at Lenten and Easter services. Similar reports are emerging in the USA, where younger people make up much of the increase. Meanwhile, France has had a 50% rise in adult baptisms, and survey data suggests a fourfold increase in Catholic observance among 18 to 24-year-olds in Britain.

Sydney Johnston grew up in a nondenominational Christian household — but now the Upper West Side millennial is a devout Catholic.

“There’s just something so beautiful and transcendent about the rituals and the ancient history in the Catholic Mass that’s been preserved,” Johnston, 30, told The Post. “The church really communicates a degree of reverence that I didn’t find in the more liberal, laissez-faire approach of nondenominational churches.”

Predict who the next pope will be at your peril.

An old Italian saying warns against putting faith, or money, in any presumed front-runner ahead of the conclave, the closed-door gathering of cardinals that picks the pontiff. It cautions: "He who enters a conclave as a pope, leaves it as a cardinal".

But here are some cardinals who are being talked about as "papabili" to succeed Pope Francis, whose death at the age of 88 was announced by the Vatican on Monday. They are listed in alphabetical order...

Pope Francis’ famous exhortation to Catholic youth just months after being elected the 266th pope of the Catholic Church in March 2013 was “Hagan lio!” — “make a mess!” Twelve years later, upon his death Easter Monday morning at age 88, it’s fair to say that Francis took his own advice, making a mess of his pontificate and leaving the Catholic Church in a state of confusion and disarray.

Pope Francis suffered two episodes of "acute respiratory failure" on Monday, the Vatican said.

The episodes were caused by a "significant accumulation of endobronchial mucus and consequent bronchospasm," the Vatican's press office said in a brief statement.

According to doctors, acute respiratory failure indicates the pope was not responding to oxygen therapy. Endobronchial mucus means there is mucus and fluid in the deep parts of the lung or lungs,...

The Holy See Press Office issued the following medical update on Pope Francis on Saturday evening:

The condition of the Holy Father continues to be critical. Therefore, as explained yesterday, the Pope is not out of danger. This morning, Pope Francis experienced an asthma-like respiratory crisis of prolonged intensity, which required the administration of high-flow oxygen...

The professed Catholic denies she has fallen afoul of Catholic teaching on abortion, while the archbishop of San Francisco disagrees. What’s next for the former speaker?

For many Catholics, learning that the Vatican has a file open on former speaker Nancy Pelosi probably isn’t much of a shock. Over the years, the congresswoman has had her differences with the Catholic Church, of which she remains a member. Most notably on abortion.

The Vatican on Tuesday issued an apology after Pope Francis’ use of an offensive word in Italian regarding seminarians who identify as gay.

Matteo Bruni, the Holy See spokesman, said in Tuesday’s press statement that the Holy Father was “aware of the articles recently published about a conversation, behind closed doors, with the bishops” of the Italian Episcopal Conference (CEI).

Pope Francis has apologised following reports that he used extremely derogatory language towards gay men.

A statement from the Vatican said the Pope did not mean to offend anyone and apologised to those who were "hurt by the use of a word".

At the Italian Bishops' Conference, the pope reportedly said gay men should not be allowed to train for the priesthood, adding there was already an air of frociaggine, which translates as a highly offensive slur.

This meeting was in private, but has been widely reported.
