Pope Francis has formally approved allowing priests to bless same-sex couples, with a new document explaining a radical change in Vatican policy by insisting that people seeking God's love and mercy shouldn't be subject to "an exhaustive moral analysis" to receive it.

The document from the Vatican's doctrine office, released Monday, elaborates on a letter Francis sent to two conservative cardinals that was published in October. In that preliminary response, Francis suggested such blessings could be offered under some circumstances if they didn't confuse the ritual with the sacrament of marriage.

The new document repeats that rationale and elaborates on it, reaffirming that marriage is a lifelong sacrament between a man and a woman. And it stresses that blessings should not be conferred at the same time as a civil union, using set rituals or even with the clothing and gestures that belong in a wedding.

But it says requests for such blessings should not be denied full stop. It offers an extensive definition of the term "blessing" in Scripture to insist that people seeking a transcendent relationship with God and looking for his love and mercy should not be subject to "an exhaustive moral analysis" as a precondition for receiving it.

"Ultimately, a blessing offers people a means to increase their trust in God," the document said. "The request for a blessing, thus, expresses and nurtures openness to the transcendence, mercy, and closeness to God in a thousand concrete circumstances of life, which is no small thing in the world in which we live."

He added: "It is a seed of the Holy Spirit that must be nurtured, not hindered."

The Vatican holds that marriage is an indissoluble union between man and woman. As a result, it has long opposed same-sex marriage.

And in 2021, the Vatican's Congregation for the Doctrine of the Faith said flat-out that the church couldn't bless the unions of two men or two women because "God cannot bless sin."

That document created an outcry, one it appeared even Francis was blindsided by even though he had technically approved its publication. Soon after it was published, he removed the official responsible for it and set about laying the groundwork for a reversal.

In the new document, the Vatican said the church must shy away from "doctrinal or disciplinary schemes, especially when they lead to a narcissistic and authoritarian elitism whereby instead of evangelizing, one analyzes and classifies others, and instead of opening the door to grace, one exhausts his or her energies in inspecting and verifying."

It stressed that  people in "irregular" unions — gay or straight — are in a state of sin. But it said that shouldn't deprive them of God's love or mercy.

"Thus, when people ask for a blessing, an exhaustive moral analysis should not be placed as a precondition for conferring it," the document said.
