The Archdiocese of Detroit this week encouraged continued prayer for the people of Ukraine, and provides information about Catholic Relief Services, which has partnered with a Ukrainian organization.

“As war devastates the lives of so many in Ukraine, we know that prayer is the most powerful way in which we can respond to this crisis, but it is not the only response we can offer,” the archdiocese said on Facebook. “There are real people with real, immediate needs that we can help meet.” 

Catholic Relief Services is working with I Am Caritas (of the Ukrainian Greek Catholic Church and the Romanian Catholic Church) to help respond to those needs, the post said.

The calls for prayer and humanitarian aid come after the Russian military invaded Ukraine on Feb. 24. As CNBC reported, if Russia establishes even "patchy" control of Ukraine, "analysts predicted refugee flows of 5 million to 10 million people from Ukraine to Western Europe.” 

An NPR report on Wednesday said around 3 million people have fled Ukraine because of the conflict. Almost 2 million of them fled to Poland. 

Catholic Relief Services responds to emergencies and disasters around the world. "We take a comprehensive approach to international disaster relief," the agency states on its website. "As experienced first responders, we provide lifesaving help to get survivors back on their feet. Then we help people obtain the tools and skills they need to manage their own recovery.” 

Pope Francis recently announced that, on March 25, he will consecrate Russia and Ukraine to the Immaculate Heart of Mary.
