How do we respond effectively as Catholics to the tragically too common circumstance of Catholics in prominent positions blatantly betraying the Catholic faith? On the intentional killing of fellow human beings, the truth about the family, the revelation about the human person made in God's image male or female, and Christ's personal identification with the hungry, thirsty, sick, naked, imprisoned, migrant, or someone otherwise in need?
There is of course no single, concrete, detailed answer applicable in every time and place with every person. As Catholics, truth and love must always be part of our response since without truth we leave others enslaved and without charity we are just a noisy gong. Prudence is always required to know best what to say, when, and how. The other theological and cardinal virtues -- faith in God, hope that people can change, courage to say things out of season, justice with regard to the real harms done, and moderation not to go too far too soon -- are always similarly helpful. There is also the indispensable guidance and assistance of the Holy Spirit and his gifts.
