Preaching to Nonbelievers

I found this article particularly interesting because it involves an outreach to people who do not believe, not necessarily  a different religion. Also, this is the first time a talk like this is going to occur in Latin America, as it is going to happen in Mexico. The idea was first proposed by Pope Benedict XVI and Pope Francis is carrying it out. I am interested to follow up on the details of the gathering.
