Blind, unbridled consumerism and selfishness — not the number of people on the planet and having children — are the root causes of the world’s problems, Pope Francis said.

Because faith in God is not abstract but impacts the way people live and interact with others, theologians must engage with experts in other fields of knowledge as they investigate and explain the Christian faith, Pope Francis wrote.

For more than 700 years, the Catholic Church has celebrated “jubilee” or “holy” years as special times to renew people’s faith and experience God’s forgiveness, particularly by going on pilgrimage.

Pope Francis’ document proclaiming the Holy Year 2025 draws special attention to the ecumenical possibilities of the celebration, especially since the jubilee coincides with celebrations of the 1,700th anniversary of the Council of Nicaea.

The document, called a “bull of indiction,” specifies that the holy year will open at the Vatican Dec. 24 this year and close Jan. 6, 2026, the feast of Epiphany. Pope Francis also asked bishops around the world to inaugurate the Holy Year in their dioceses Dec. 29 this year and celebrate the conclusion of the Jubilee locally Dec. 28, 2025.

New York Attorney General Letitia James sued Heartbeat International, an anti-abortion group, and 11 crisis pregnancy centers May 6, accusing them of misleading and potentially causing harm to women by claiming that they can provide a treatment that reverses the effect of the abortion pill mifepristone.

While the forces of a market economy may obstruct people from advancing social justice, society cannot remain mute in the face of unjust labor practices and exploitative economic structures, Pope Francis said.

The world is in great need of hope and patience, Pope Francis said at his weekly general audience.

The Dicastery for the Doctrine of the Faith will publish its new norms for the discernment of apparitions and other supernatural phenomena May 17, the Vatican press office said.

Loneliness causes tremendous harm, including to families, Pope Francis told international leaders of the Teams of Our Lady lay movement.
