I see it as an approach of legalism vs. an approach of accompaniment.
There are certain Catholics who would rather think in black-and-white terms all of the time, because it’s easier to just throw out rules and stick to definitions.
I admire the approach Francis is taking the church, and no, he is NOT changing doctrine. The fact of the matter is, every single person is at a different stage in life. You can point out that some action is objectively wrong, but if that’s all you do – even if you proceed from there – you do a grave injustice to the person at the heart of the matter.
Even with divorce. Yes, divorce and remarriage is inherently wrong and against Christ. But when you get to real people and real situations, it does indeed become more complicated. Did this person even know what is meant by Christian marriage? Even if they are remarried, what are the psychological and social circumstances that could have led up to this? Is it reasonable to think that a supposed relationship will end, that looks objectively wrong on the outside, without destroying an individual’s life in the process?
