“The Lord has redeemed all of us, all of us, with the Blood of Christ: all of us, not just Catholics. Everyone,” the pope told worshipers at morning Mass on Wednesday. “‘Father, the atheists?’ Even the atheists. Everyone!”

Francis continued, “We must meet one another doing good. ‘But I don’t believe, Father, I am an atheist!’ But do good: we will meet one another there.”

Roy Speckhardt, executive director of the American Humanist Association, said that although he has been skeptical of Francis' outreach to the nonreligious, he welcomed Wednesday’s comments.

“I gather from this statement that his view of the world's religious and philosophical diversity is expanding,” Speckhardt said. “While humanists have been saying for years that one can be good without a god, hearing this from the leader of the Catholic Church is quite heartening."

He continued, “If other religious leaders join him, it could do much to reduce the automatic distrust and discrimination that atheists, humanists, and other nontheists so regularly face. “

Francis’ comments received a great deal of attention on social media, with a number of people asking whether the Catholic leader believes that atheists and agnostics go to heaven, too.

On Thursday, the Vatican issued an “explanatory note on the meaning to ‘salvation.'"
