Does this mean going to convince someone to become became Catholic? No, no, no! You are just reaching out to meet him, he is your brother! That is enough. You reach out to help them, the rest is done by Jesus, by the Holy Spirit. Pope Francis.
I'm just the messenger; Pope Francis is the author.
I don’t think you’re a faithful messenger. I didn’t see you deliver this message:

Second sentence: he doesn't mean you NEVER convince him to be a Catholic. Just reaching out and helping your brother, neighbor-love, may well be enough --- it may be literally all you can do --- at some time, in some place, or with some particular person. (Then, as the Pope's insight suggests, you pray for the Holy Spirit to do the rest.)
When Jesus commanded us, "Go and do likewise," he was talking about a Samaritan who responded compassionately and helped a Jew. This defines what neighbor-love is. This is Scripture. It's not anti-Evangelical. It is the Evangelion.
