“Aside from the differing ways that various countries responded to the crisis, their inability to work together became quite evident,” Francis wrote. “Anyone who thinks that the only lesson to be learned was the need to improve what we were already doing, or to refine existing systems and regulations, is denying reality.”

He cited the grave loss of millions of jobs as a result of the virus as evidence of the need for politicians to listen to popular movements, unions and marginalized groups and to craft more just social and economic policies.

“The fragility of world systems in the face of the pandemic has demonstrated that not everything can be resolved by market freedom,” he wrote. “It is imperative to have a proactive economic policy directed at ‘promoting an economy that favours productive diversity and business creativity’ and makes it possible for jobs to be created, and not cut.”’

As an outgrowth of that, Francis rejected the concept of an absolute right to property for individuals, stressing instead the “social purpose” and common good that must come from sharing the Earth’s resources. He repeated his criticism of the “perverse” global economic system, which he said consistently keeps the poor on the margins while enriching the few — an argument he made most fully in his 2015 landmark environmental encyclical “Laudato Sii” (Praised Be).

Much of the new encyclical repeats Francis’ well-known preaching about the need to welcome and value migrants and his rejection of the nationalistic, isolationist policies of many of today’s political leaders.

“It is very difficult nowadays to invoke the rational criteria elaborated in earlier centuries to speak of the possibility of a ‘just war,’” Francis wrote in the most controversial new element of the encyclical.
