As Russian tanks and troops moved to attack Kyiv and explosions were heard across Ukraine’s capital city, Pope Francis spoke by phone with Ukrainian President Volodymyr Zelensky this Saturday afternoon, Feb. 26.

On this “Inside the Vatican” episode, host Colleen Dulle and veteran Vatican correspondent Gerard O’Connell examine the religious aspects of the Russia-Ukraine conflict.

In a visit with few if any precedents, Pope Francis met with the Russian ambassador to the Holy See this morning to express concerns about Russia's ongoing invasion of Ukraine.

What do my prayers for Ukraine achieve? Is this about convincing God to intervene or softening my own heart so I can suffer with my Ukrainian brothers and sisters?

A “just war” in Ukraine would be a catastrophe for all parties. But a “just peace” framework that recognizes the root causes of the conflict can bring the U.S., Russia and Ukraine to a mutually beneficial outcome.

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.
