he speculation over who will be the next pope is often a preoccupation of the Italian press and the subject never really fades away.

Newspapers up and down the peninsula love to handicap the race among the cardinals who are thought to be the most likely candidates to be elected pope. Indeed, the Italian term “papabile,” coined by Vatican watchers, has become mainstream over the last few decades.

Which man is “pope-able” (that is, able to become pope) is often debated in Rome and anywhere Roman Catholics gather.

Who will follow Pope Francis? The pontiff turns 84 in December, fueling speculation over who will be his replacement once he dies and the College of Cardinals meets to elect a new leader. Of course, there is now the possibility that he could retire — like Pope Benedict XVI.

A new book out, “The Next Pope: The Leading Cardinal Candidates” (Sophia Institute Press) by the National Catholic Register's longtime Rome correspondent Edward Pentin (you can read his wonderful work here), delves into the lives and beliefs of the cardinals most likely to ascend to the Chair of St. Peter. Extremely well-researched (thanks to the help of international scholars), this book is a must-read for all Catholics and anyone who wants to take a peek into what the future and what personal experiences and philosophies these various men bring to the table.

In all, Pentin helped to pinpoint 19 men who could replace Francis once his pontificate is over. Becoming the spiritual leader of more than one billion Catholics worldwide and one of the most influential moral and religious figures in the world isn’t a matter to take lightly. What this book does well is offer up an in-depth look at these cardinals (their ecclesiastical life as priests and later bishops), many of whom remain unknown to most people — journalists included.

The events of the past few days have truly been monumental for the Roman Catholic church.

You may not have noticed — unless you’ve bothered to read the ever-growing list of Catholic news websites on both the right and left. While liberals and conservatives within the church continue to wage a very public war over everything from the future of Christendom in the West to the ongoing clerical abuse crisis, two prominent voices have led the charge when it comes to these two issues.

Again, it was conservative Catholic media that proved to be the preferred mouthpiece for Cardinal Robert Sarah and Pope Emeritus Pope Benedict XVI. Both men — with help from right-leaning news organizations — have been very vocal about the problems plaguing the modern church in our ever-secular world.

It is fitting that these two men — one considered a potential future pope, the other already a pope — are the ones leading the charge as the church continues to become polarized. Under Francis’ papacy, the ideological split has become more pronounced. As the curia continues to polarize itself in public on issues like immigration and homosexuality, church leaders like Sarah and Benedict refuse to be silenced. Once again, it’s those Catholic media voices on the right that are helping to spread their message.

Case in point: this past week. At a time when Christians around the world continue on their Lenten journey, Sarah and Benedict are making a statement about the direction of Catholicism, the legacy of Vatican II and where the church is going. Sarah, who hails from the majority-Muslim nation of Guinea in Africa, contrasted Pope Francis’ statements in telling Christian nations they should open their borders to Islamic refugees.

The 73-year-old cardinal, in his new book” Evening Draws Near” and the “Day is Nearly Over,” argues that it’s wrong to “use the Word of God to promote migration.” Sarah laments the “collapse of the West” and what he calls “migratory processes” that threatens Europe’s Christian identity. As birthrates continue to drop across Europe, and workers from other continents are needed to take jobs, the culture of the continent is changing.

“If Europe disappears, and with it the priceless values of the Old Continent, Islam will invade the world and we will completely change culture, anthropology and moral vision,” he wrote.It’s worth noting that Sarah has been at odds with Pope Francis and his allies over an array of issues, including liturgical matters and translations of Latin texts.

The excerpt was largely ignored by mainstream news outlets.
