To answer God's call to holiness, Christians must care for the poor, the sick and the immigrant just as they care for preventing abortion, Pope Francis wrote in his latest major guidance, published on Monday.

The document, titled "Gaudete et Exsultate" (Latin for "Rejoice and Be Glad"), is Francis' third major publication in his five-year papacy, following works on the environment and the ­family that each made waves in the Roman Catholic Church. This apostolic exhortation takes up a broader theme, holiness, but some church scholars quickly read the new work as an implied response to the pope's conservative critics.

Francis writes of what it means to be holy in the modern world, with many specific examples: viewing a person sleeping on the street not as an obstacle or a political problem but as a human; reading the Bible even in a time of constant online distractions; avoiding being "caught up in networks of verbal violence through the internet."

Francis's vision of holiness is expansive, touching on the actions of everyday people in situations from family life to politics. "It goes back to Genesis, which says all of us, all of creation, all men and women are made in the image and likeness of God. What Pope Francis is trying to say is: Do we really believe that?" said the Rev. William Graf, chair man of religious studies at St. John Fisher College in New York. "Do we see God present in the immigrant? Do we see God present in the gay person?"

Conservatives in the church, in particular a small group of U.S. cardinals who have written about their concerns with Francis' 2016 apostolic exhortation that gestured toward a more forgiving stance on divorce and remarriage and other issues regarding families, will likely not be appeased.

"It will not make liturgy traditionalists very happy," said the Rev. James Bretzke, a theologian at Boston College. Bretzke sees Francis' discussion in the new document of contemporary thinkers who fall into age-old errant patterns of thought known as Gnosticism and Pelagianism as a rebuke of the conservative cardinals. "He's saying to these people that they might be falling into contemporary versions of ancient heresies."

Bretzke said that Monday's document seemed to implicitly reply to doubts published by the conservative cardinals. "Their question is, 'Do we still believe in an objective moral order?' … That's always been the Christian conundrum. If God is perfect and holy, shouldn't we be absolutely perfect and absolutely holy?" Bretzke said. "What Pope Francis responds: God is everywhere. God is in Syria. God is in the Sunday church. God is in an abortion clinic. God is with the immigrants. When you try to find God there, then you're going to be cooperating more effectively with God. Holiness doesn't mean being just pure and away from the world and away from other people. Holiness means being whole, and you can only be whole as a human person in a community of persons."

Reading Francis' new writing on Monday and comparing it with the pope's first major writing, his encyclical on the environment, Graf noted that the pope devoted a large portion of this new work to the Beatitudes, the famous passage in Matthew that says the meek, the mourning, the merciful, the peacemakers and the persecuted are blessed.

Francis concludes that "the great criterion ... on which we will be judged" is found at the conclusion of the Beatitudes: "I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, I was naked and you clothed me, I was sick and you took care of me, I was in prison and you visited me."
