In his comments to CNA, Archbishop Loro said that from a religious point of view, "the three of us as different religions, all are Christian religions and we are perfectly together."
Different Christian communities have always spoken about the situation of the country together, he said, explaining that it's "perfectly in place" that the three of them would come to the Vatican together to voice concerns surrounding the state of their country.
"We are together and we are really speaking one voice and one language" to raise awareness of the humanitarian, political and social crisis of the country both locally and internationally.
In light of the ongoing Jubilee of Mercy, the necessity for forgiveness and acceptance of others was underlined as a key path to building peace and fostering human development, according to the communique.
The three Christian leaders stressed their commitment to working together "a spirit of communion and unity, to service to the population, promoting the spread of a culture of encounter and sharing."
Sudan has been the scene of nearly continuous civil war since it gained independence in 1956. Many of the initial problems were caused by corruption in the government, which led to the political, economic, and religious marginalization of the country's peripheries.
South Sudan became an independent country in 2011 but it has been torn by a civil war since December 2013, between the state forces – the Sudan People's Liberation Army – and opposition forces, as well as sectarian conflict.
A peace agreement was signed but it was broken by violence earlier this summer, which prompted the South Sudan Council of Churches to publicly condemn the violence and pray for peace. A ceasefire was then ordered by President Kiir and then-Vice President Machar in July.
Machar, the former rebel leader, ended up fleeing the country, but despite this, some fighting has continued in the country.
Although South Sudan is now independent from Sudan, the two countries share an episcopal conference. South Sudan also shares a common apostolic nuncio with Kenya, Archbishop Charles Daniel Balvo.
This point was also brought up during their meeting with Pope Francis, Archbishop Loro said, explaining that when the Pope asked how it was working out to have a shared nuncio between the two countries, he requested that South Sudan have its own.

The three Christian leaders extended an official invitation to Pope Francis to visit the country, particularly as a sign of solidarity and peace.
Francis said he would like to go if possible, Archbishop Loro said, explaining that he Pope's visit "would be the visit of a religious leader to the country."
Given this fact, the visit "would have a great impact and would be very welcome by us and by civil society, and it would be a great help for us. This is why we came to the Pope," he said.
