The Vatican's Santa Marta guesthouse has 128 rooms. From 7 May, it will be filled with cardinals participating in the conclave to elect the next Pope. But one room in the guesthouse is still sealed with a red ribbon, as it has been since its occupant died there on Easter Monday.

That suite will only be reopened when the new pope is chosen. The ribbon remains a tangible reminder of the man whose shoes the cardinals are looking to fill – but Pope Francis' presence looms large over this conclave in many profound ways.

He spent 12 years in the role and appointed around 80% of the cardinals who will select his successor. He also looked to radically shake up the workings of the Catholic Church, moving its centre of gravity away from its hierarchy at the Vatican in the direction of the rank-and-file faithful all over the world, and focused on the poor and marginalised.

My conversations with cardinals and those assessing the needs of the Church in the days leading to this papal election almost always end up looking at what is required through the prism of what Pope Francis did in the role.

While in recent days there appears to have been a growing coalescence around the idea that Francis' work should be built on, some of his critics remain far from convinced. So might there be enough of them to sway the vote as the Church attempts to reconcile the different outlooks and realities it faces around the globe?

A most diverse conclave

During the two weeks that followed the Pope's death, the cardinals met almost daily at the Vatican for pre-conclave gatherings known as general congregations.

While the conclave in the Sistine Chapel is limited to cardinals who haven't yet reached the age of 80 (133 will participate in this one), these preliminary meetings are open to all 252 cardinals. Each attendee was given up to five minutes to air their views, though we know that some took longer.

It was during such a meeting ahead of the last conclave of 2013, in a speech lasting less than four minutes, that Pope Francis – then known as Cardinal Jorge Bergoglio of Argentina – made an impact, talking of a need to connect with those in the far reaches of the Catholic world.

As Pope, he made a conscious drive to appoint cardinals from such places. It is why this is the most diverse conclave there has ever been. For the first time Cape Verde, Haiti, South Sudan, Tonga, Myanmar, Papua New Guinea and Rwanda will be represented.

That diversity has already made its mark: the pre-conclave meetings are said to have brought to the fore just how different the needs of the Church appear to be depending on where in the world they are viewed.

In Europe, for example, a primary consideration for some might be finding ways to reinvigorate and make relevant the mission of the Church in the face of shrinking congregations, whereas elsewhere – in African or Asian countries – concerns may revolve around social issues, poverty and conflict resolution.

A prospective pope is likely to be one who has at least shown recognition of those very different realities.

Spiritual leader, statesman, global influencer

The official titles that the new pope will inherit gives a sense of the breadth of the role: Bishop of Rome, Vicar of Jesus Christ, Successor of the Prince of the Apostles, Supreme Pontiff of the Universal Church, Sovereign of the State of Vatican City among them.

While some relate to the deeply spiritual, the last of those titles suggests the need for a statesman too, given that the pope is leader of a country, albeit the world's smallest.

"Unlike your average state, the agenda of the Vatican is driven to an extent by where the pope reigning at the time puts their emphasis," says Chris Trott, British ambassador to the Holy See. "On the face of it a very tiny state, [but it is] one that punches many, many times above its weight.

"And Pope Francis had 50 million followers on Twitter, so [it is] a very, very small state and an incredible global influencer."

Pope Francis chose to amplify this part of the role, becoming a powerful global spokesman on behalf of those on the margins, including the poor and victims of war.

He also tried to play the role of peacemaker, though not everyone thought he was successful in that regard, in relation to China and Russia in particular.

According to Cardinal Vincent Nichols, the most senior Catholic figure in England and Wales, this expansion of the role is one reason so many even outside the faith are invested in the outcome of the conclave.

"There is a sense that the Pope in the person of Pope Francis became a figure who addressed everybody in the world… religious people and even those who do not have a religious affiliation," he says.

"I'm more and more aware that it's not just Catholics who are interested in this."

Confusion around Pope Francis' vision

For many voting cardinals, it is primarily issues within the Catholic Church that are under the spotlight, which brings about the question of the type of pope they want as a manager, and someone who runs the Church's administrative body and its ministries.

While Pope Francis worked on improving the way the Church deals with the huge issues of sexual abuse and of financial corruption, it is his successor who will have to ensure that reforms are evenly applied across the Catholic world.

Even supporters of Pope Francis' efforts to make changes to the way the Church relates to its rank-and-file believers, and the way he built bridges with those outside the faith, were sometimes left confused about how exactly he envisioned things should work.

Pope Francis changed the tone on social issues through comments he made, talking openly about subjects ranging from climate change to financial transparency within the Vatican. But throughout his papacy, some were unclear about what he meant or how it would be applied.

One mission he had was to take some of the power and decision-making away from the Vatican hierarchy and into the hands of rank-and-file Catholics.

Over nearly four years, at great effort, he commissioned what was, in effect, a poll of many of the world's Catholics to find out what mattered to them. Lay people were invited to participate in the most recent bishop's conference where the results of the survey were discussed.

The biggest issues raised related to greater roles for women in the running of the church and welcoming LGBT+ Catholics. But the meeting ended in some confusion, with little in the form of tangible steps forward and little clarity as to how lay people will help steer the future direction of the Church.

So, there is a general keenness for greater clarity from the new pope.

An ugly divide: supporters and detractors

Throughout his pontificate, some vocal traditionalists opposed what they saw as Pope Francis straying from Church teaching and long-standing tradition.

In the pre-conclave meetings of cardinals, a number of those over the age of 80 (who because of their age would not be involved in voting) took the opportunity to play their part.

Most contributions remained secret, but one that was reported was that of 83-year-old Italian cardinal, Beniamino Stella. He criticised Pope Francis for "imposing his own ideas" by attempting to move Church governance away from the clergy.

And yet during the homily, or religious speech, at Pope Francis' funeral, what appeared to resonate with the public in attendance – judging by the volume of the applause – was talk of the themes Francis chose to champion: the dignity of migrants, an end to war, and the environment.

This applause would have been heard loud and clear by the rows of cardinals.

In some senses, Pope Francis did have clarity in focusing on the Church being relevant to people in their daily lives and, indeed, their struggles. He was clear about connecting with the world outside the faith too.

"There is a sense that in the voice of the pope, there's a voice of something that is needed," says Cardinal Nichols. "For some people it's a moral compass, for some people it's the sense of being accepted, for some people it's the insistence that we must look at things from the point of view of the poorest.

"That's a voice that has fallen silent and our task is to find someone who can carry that forward."

From the death of Pope Francis to the moment cardinals checked into the Santa Marta guesthouse and its overflow residences, there appeared to be a trend towards a desire for continuity of what Pope Francis had achieved.

Though perhaps that vision of continuity is one that could bring along more of his sceptics, in a way that was pragmatic. The word "unity" has been talked of a lot, after a period where the divides between supporters and detractors of the Pope's vision could sometimes become ugly.

But in the end, when they step into the Sistine Chapel, the holiest of voting chambers, for all the pragmatism they may have taken into consideration before they cast their ballot, they will be urged to let God and the Holy Spirit guide them.
