“And we all have a duty to do good. And this commandment for everyone to do good, I think, is a beautiful path towards peace,” Francis continued. “If we, each doing our own part, if we do good to others, if we meet there, doing good, and we go slowly, gently, little by little, we will make that culture of encounter. We need that so much.”
“We must meet one another doing good,” the Pope asserted. “‘But I don’t believe, Father, I am an atheist!’ But do good. We will meet one another there.” (link)
The Pope is of course equivocating two vital terms ("Sons of God" and "meeting there") to teach universalism or at least an extremely wide inclusivism. The Bible names us God's sons in at least two ways: 1) via creation and 2) via adoption (contrast Acts 17:28-30 with Romans 8:14). Likewise, the Pope's saying "meeting there" at one point means agreement about charitable works and at another point it means heaven. (In this posts' title, I am using there in a third way - I mean hell.) So by a play on words, conservative Catholics can take the Pope's words to mean Christ died for everyone, God created everyone and we can work along side atheists for good and liberal Catholics can take the Pope's words to teach all paths lead to heaven.
For James White to link the Pope's comments here with Arminianism is basically to teach it's OK to take Arminianism out of context. (link)
