Many people dismiss the Church's flaws as 'the humanity of the Church.' But the problem isn't the Church's humanity; it is the Church's inhumane practices and those who are more faithful to the institution than they are to the Gospel message of love. It is those practices that are causing the institution, beloved by so many, to become less credible as a spiritual authority in the world.
Most of us can deal with human error and sin. What we can't deal with is an institution that presents itself as holier than thou and ends up having a lot more skeletons in its closet than it is willing to admit.
