On the one hand, I'm in agreement - and I said this before the Pope's election - with the idea that the communication of orthodox teaching on various sins, particularly sexual ones, could be done better than it currently is. I think the orthodox response, in terms of rhetoric, has been pretty abysmal for a long time.
On the other hand, I realize that 'we have to change our tone' is a pretty common progressive trojan horse. Whereas I think it means treating people more civilly, more reasonably, other people try to rework it into 'Make active unrepentant homosexuals feel welcome at your church! Hug them and apologize to them on behalf of all Christianity for what are largely imaginary sins! Say that the REAL crime of abortion is that the middle class 27 year old who's gotten one three times to cover adulterous affairs isn't treated with enough respect!' Those are rotten people, and yes, they really do exist.
So it's a great Catch-22. Adjust your tone, and embolden dishonest, progressive shits. Refuse to adjust your tone, and continue to communicate poorly. Charting the proper course between these two extremes isn't easy, but if it's necessary, what else can you do but try?
