The short answer is "No". Not "not really"; not "not in so many words". Just "no".
In just a few months, a pattern has been set such that the ineffable Fr. John Zuhlsdorf could start a companion blog named "What Did the Pope Really Say?" and not run out of material for awhile. It seems that now a month can't go by without Papa Bergoglio saying something the Vatican has to explain or walk back. The mainstream press has cast the "progressive pope" filter in concrete, and will continue to run his impromptu remarks through it until he dies or relinquishes the Chair of Peter.
It doesn't help that Papa's words sometimes take three or four readings to get clear ... especially if you have to rely on Zenit's English translation, which is only marginally better than Babelfish. When he was elected, Marcelo González of Panorama Católico Internacional sneered, "Famous for his inconsistency (at times, for the unintelligibility of his addresses and homilies), accustomed to the use of coarse, demagogical, and ambiguous expressions, it cannot be said that his magisterium is heterodox, but rather non-existent for how confusing it is." His unique, populist style sometimes gets in the way of his clarity of expression.
Maybe he should get his new head of the CDF, Abp. Gerhard Müller, to proofread these things. Or, there's supposed to be a rather eminent and well-respected theology professor living in retirement at the Vatican ....
Let's start with the context. Eugenio Scalfari, editor of La Repubblica and a non-believer, published three questions for the Pope, to which Francis responded in an open letter. After setting some initial ground work, Francis wrote:
It seems to me that, in the first two, what is in your heart is to understand the attitude of the Church to those who don’t share faith in Jesus. First of all, you ask me if the God of Christians forgives one who doesn’t believe and doesn’t seek the faith. Premise that — and it’s the fundamental thing — the mercy of God has no limits if one turns to him with a sincere and contrite heart; the question for one who doesn’t believe in God lies in obeying one’s conscience [bold font mine.—TL]. Sin, also for those who don’t have faith, exists when one goes against one’s conscience. To listen to and to obey it means, in fact, to decide in face of what is perceived as good or evil. And on this decision pivots the goodness or malice of our action.
The context here is not about atheism specifically, but rather about non-Christians in general. In fact, the question is closely tied with another Scalfari asked about Jews. Moreover, the question was about forgiveness, not heaven, though the two concepts are tied together. However, these distinctions were lost on the press, who proceeded to announce that Pope Francis had opened heaven to atheists, causing orthodox facepalming and Evangelical howling (as exemplified by the noted prophet and theologian Kirk Cameron, who got it wrong, too).
