That is not the same thing. AA and similar groups are there for people with severe problems of addiction and so on. For people in difficulty. The Catholic church is supposed to be just that - catholic - all-encompassing, appealing to all Christians. Its teachings are supposedly based on those of Jesus. Those teachings emphasised goodness, kindness to neighbours, humility, the eschewing of excessive wealth, help for people in need and mutual respect. According to Joe's analysis, The world outside Catholicism, two thousand years after Jesus, is just about the same as within it. Therefore "what's the point of it?" seems a valid question to me.
