I don’t think he’s ambiguous. He has a message, which is that he wants people to convert and he doesn’t want them to think about it in political terms or even really in the way that the press always presents the Church (repressive, rigid, etc.). He wants them to meet the Lord.
I don’t think, however, that he always considers how the enemies of the Lord will twist things.
On the other hand, BXVI said very little officially, except for the audiences, and gave few live interviews. But even so, the press managed to distort one of them to the point of making it sound like an attack on Catholic doctrine, and made his scholarly Regensburg address sound like he was calling out the Crusaders. So there’s really not much that can be done about this.
If Jesus had waited until he thought he’d be understood, he wouldn’t have been able to open his mouth.
He is converting souls that have been lost for a long time. The rest is just collateral damage. He is not preaching to the converted in fact he is saying, “He who has no sin . . . “ to the faithful and he is right to do so. The evil one will always do evil. It never stopped Jesus from doing the tough work. The evil one will always twist everything but it will reach many souls and already has reach millions that would never even mention the word Catholic or pope. He is the talk of the globe now and his message is getting deep into peoples craws that would never have otherwise. The present faithful already have the foundational tools of Christ and need to pick them up and get to work.
