"Fraternity among Catholics is wounded," Cardinal Raniero Cantalamessa said. "Divisions between churches have torn Christ's tunic to shreds.”

Climate change and environmental destruction are forcing millions from their homes, and Catholics have a responsibility to assist them, Pope Francis wrote.

The pope in late February accepted the resignation of Guinean Cardinal Robert Sarah, who had reached the normal retirement age of 75 last June. The cardinal had been prefect since 2014.

“Jesus announces to us that God is not an idea or an abstract doctrine, but God is the one who ‘contaminates’ himself with our human woundedness and is not afraid to come into contact with our wounds,” the pope said.

"[Vatican II] is the magisterium of the church. Either you are with the church and therefore you follow the council, or if you do not follow the council or you interpret it in your own way, as you wish, you are not with the church."

"I am the pastor of people who are suffering," Pope Francis said.

The first 25 shelter residents were vaccinated Jan. 20, the Vatican said, and more will be given the vaccine in the coming days.
