From the archbishop's letter:
I write with a growing sense of urgency about recent actions taken by your Administration that both escalate the threat to marriage and imperil the religious freedom of those who promote and defend marriage...
The Catholic Bishops stand ready to affirm every positive measure taken by you and your Administration to strengthen marriage and the family. We cannot be silent, however, when federal steps harmful to marriage, the laws defending it, and religious freedom continue apace...
I know that you treasure the importance that you and the First Lady, separately and as a couple, share in the lives of your children. The Mother‟s Day and Father‟s Day proclamations display a welcome conviction on your part that neither a mom nor a dad is expendable. I believe therefore that you would agree that every child has the right to be loved by both a mother and a father.
The institution of marriage is built on this truth, which goes to the core of what the Catholic Bishops of the United States, and the millions of citizens who stand with us on this issue, want for all children and for the common good of society. That is why it is particularly upsetting, Mr. President, when your Administration, through the various court documents, pronouncements and policies identified in the attached analysis, attributes to those who support DOMA a motivation rooted in prejudice and bias. It is especially wrong and unfair to equate opposition to redefining marriage with either intentional or willfully ignorant racial discrimination, as your Administration insists on doing.
We as Bishops of the Catholic Church recognize the immeasurable personal dignity and equal worth of all individuals, including those with same-sex attraction, and we reject all hatred and unjust treatment against any person. Our profound regard for marriage as the complementary and fruitful union of a man and a woman does not negate our concern for the well-being of all people but reinforces it. While all persons merit our full respect, no other relationships provide for the common good what marriage between husband and wife provides. The law should reflect this reality.
