VATICAN CITY, Jan. 1 (UPI) — Pope Francis, during his New Year’s address Wednesday to tens of thousands of people in St. Peter’s Square, called on people to build a more just world.The pope said he hopes the new year will bring peace, justice and liberty to the world, Vatican Radio reported.

“Peace requires the force of meekness, the force of nonviolence of truth and of love,” he said.

He noted the church is celebrating the feast of Mary and the World Day of Peace Wednesday.

He called for people to acknowledge violence and to work toward building a just society during his address, titled “Fraternity: the Foundation and Pathway to Peace.”
