That's Monsignor Charles Pope of the Archdiocese of Washington. The Cardinal Newman society gives the background:
"If you haven't heard yet, a federal agency decided that (Catholic) Manhattan College could not prevent faculty from unionizing on the basis that it is a religious institution. Despite acknowledging that the College is recognized as Catholic by the New York Archdiocese, the National Labor Relations Board reviewed College statements and course content, finding 'that the purpose of the College is secular and not the 'propagation of a religious faith'."
The Monsignor writes:
"The fact is that the Church is to be a light to the world, but it sometimes happens that we fall short and God must allow the world itself to rebuke us. The Christian community is supposed to be self-correcting. It is an embarrassing truth that it sometimes takes Caesar to tell us to give to God what is God's, to be more serious about our Christian walk, and to be true in our claims to be Catholic."
"But the moral lesson in these cases seems to be that we had better get our own house in order. Certain 'Catholic' Colleges may go on for a while gleefully dissenting and ignoring Church mandates, but in the end they are going to be called to account by Caesar who will say, 'Either give God what God is due, or stop pretending and pay the taxes that every other secular organization pays and observe the requirements every other secular entity does.' In other words, decide what you really are and do so quickly."
"For the state to respect the rights of Catholics, Catholicism has to be intelligible. Hence these dissenters also endanger the religious freedoms of those who are faithful. Yes, we need to get our house in order."
