I think the mistake Bishop Tobin makes is to confuse the vehicle with the passenger. We are called to believe in God through the gospel of Jesus. The Church is simply the vehicle by which God and gospel come down to us. When that vehicle functions as it should, it brings God and gospel to the people. When it malfunctions, it sets up shop and invites the people to come to it, largely on its own terms, which is what I read Bishop Tobin's comments to imply: young people should remain in the Church because the Church has the sacraments. The sacraments, by definition, are not grace, but vehicles of grace and, as such, they are meant to bring God to the people. Once again, the Bishop assumes the sacraments are the possession of the Church and the people should come to it, whether the Church speaks their language or not, whether the Church is a flawed vehicle and countersign of faith or not. As a result, he sees tens of millions of Catholics leaving the Church and thinks he's just fine.
