One difficulty with giving Mrs Bush the free hand she has is that, as I've mentioned, she didn't begin attending St Mary's until early 2011. Prior to that, she hadn't attended church at all for 40 years, since her late husband had disapproved of religion. We may surmise that Mrs Bush used this time in learning how to achieve social prominence, not in the prayers and sacraments. Consequently, I think she views St Mary of the Angels as less a church than a chapter of an exclusive social club. This probably explains the bitter anger of Mrs Bush's small clique at the much wider membership of the parish.
But for Bishop Marsh to ignore what's happening in the parish is simply a recipe for disaster. I'm just a lay person, but my experience in the corporate world has given me many examples of why those in charge need to stay in touch and keep track of things, because cobwebs grow in undusted corners, and things can veer out of control at unexpected times. Winging it is never a good strategy. Word to the wise, Bishop Marsh.
