I find it interesting to see that certain Catholics had been complaining that the Church never talked about sin...
...yet, when the Pope speaks out about sins against charity it is easy for the affluent westerners to commit, these same Catholics get offended.
Perhaps they were more interested in seeing the Church condemn other people than to hear what we need to do to grow closer to Christ.
That's not to say those other sins are unimportant of course. But everyone should ask themselves whether they are concerned with salvation or vengeance.
