Pope Francis has confirmed that members of the Fraternity of St. Peter may continue to celebrate the Mass, sacraments and Liturgy of the Hours using the pre-Vatican II texts and forms, the fraternity said.

This week on “Inside the Vatican,” veteran Vatican correspondent Gerard O’Connell and host Colleen Dulle explain the changes to the C.D.F. and how they fit into Pope Francis’ larger goal of evangelization.

Addressing a symposium on the priesthood in the Vatican on Feb. 17, Pope Francis presented what he called the “four forms of closeness” that he considers fundamental to the life of a priest.

“To be a Christian is not only to receive the faith, to confess the faith, but to safeguard life, one’s own life, the life of others, the life of the Church,” Pope Francis said in his Wednesday audience.

Just war principles do not require Western nations to practice pacifism or ignore Russian aggression in Ukraine. But they may still guide nations to a nonviolent resolution, and Pope Francis can help.

In an important move, Pope Francis has issued a decree, published “motu proprio” (on his own initiative), in which he has modified the internal structure of the Congregation for the Doctrine of the Faith.
