The thing that actually makes religions different from each other in terms of whether they are known for their tolerance of others is:
1. What they believe the consequences of being "less than right" is. ie - do you believe that everyone else is going to Hell or do you believe that in the end we all end up in the same "place" or do you believe something in between?
Well it's quite possible to say that you are the One Holy Catholic and Apostolic Church and that other churches are not in the Church as such without holding that their members are damned or that they aren't Christians. That's the position we hold and, i believe, is the position held by RCs as well. Sometimes, I think, Protestants have difficulty understanding this precisely because for them the Church is invisible and consists of all believers - so it sort of is synonymous, in Protestant terms, with salvation. That's absolutely not the case for those of us who do believe we are members of the one visible Church. Ironically, I tend to find that those who hold to the post-Reformation invisible Church idea tend to be less tolerant than we who do not, despite their protestations when we state our beliefs.
2. How often they talk about it. ie - when speaking with others, do you focus on what's different or what's held in common? Do you see others as sisters and brothers who are maybe slightly mislead but ultimately still your family, or do you see "the other"?
I know what you mean, but genuine dialogue requires honesty even when, at times, that honesty is unwelcome, hence the fact that, despite the criticism of the Church by this Pope, I welcome this statement. If he were to 'rub it in' in some triumphalist manner, that would be different, but I get no hint that this is anything more than the Pope of Rome's attempt to be honest in setting boundaries.
Did JPII believe ultimately that the Catholic Church is the right Church? Of course he did. That went without saying...literally. The question still is, as lunamoth asked, why is Ratzinger making a point of talking about it now?
Well, personally, I think that this is about, along with the recent announcement on the Tridentine Mass, an atempt to heal divisions within his church. The fact that it has welcome consequences for us or unwelcome ones for others is not, I don't think, the Pope's point in making it. Either way, I just welcome the clarity and hope that our heirarchs respond in kind and make it equally clear where the line we shall not cross is - then maybe some of the more 'pie in the sky' Orthodox and RCs who are ready to ring the bells (or beat the toacas) to usher in the news of reconcilliation might get real.
