I have reflected a great deal on that event, and continue to do so. I cannot give you a complete answer in a few sentences. But I would say that I was struck at that time by the vehemence of the anger from various sides, and the anger was in many cases directed at those who share a Catholic faith. I understand that such anger, such vehemence arises from sincere and passionate conviction, but I believe expressing it in such vitriolic terms gets us nowhere.

[Pope Francis] has reminded us that the way we live our lives is the most important expression of our Catholic identity.

I live near Amish communities in northern Indiana and I have the greatest respect for such faithful people. They attempt to live their faith more fully by separating themselves, as far as possible, from the wider culture and its influences. That has never been the teaching of the Catholic faith.

[Pope Francis] has done this not through angry speeches, but through the powerful symbols and examples of embracing a badly deformed man, welcoming refugees to the Vatican, strolling through a shanty town in Rome, visiting a home for the elderly, washing the feet of prisoners on Holy Thursday, and going to a hospital for newborns.

I've seen many dig in their heels and becoming disenchanted with the church because of these kinds of denunciations from coreligionists. We have to find a better way to witness to our faith and our convictions.

But rather than trying to understand and rise above them, as leaders should, the [presedential] campaigns have often simply channeled these negative emotions. This has made the substance and tone of much of the discussion not only unpleasant and uninspiring, but the acrimony and divisiveness are not healthy for our democracy.

We are called to serve the common good by engaging with political and other institutions, even in our pluralistic society. We bring to that effort Christ's command to love and the grace that helps us live that love.
