Christ the King and "Quas Primas"

In my experience, preachers in Catholic parishes don't know quite what to do with the Feast of Christ the King, which is today.  Usually, the day's "message" or "theme" has been (again, in my experience) something to the effect that we should ask if we are "putting Jesus first in our lives/hearts" (and, certainly, we should). 

And yet . . . especially in light of the emerging (and much needed) focus in the Church on religious liberty and the realities of both aggressive secularism and persecution, it's worth (re-)reading Quas Primas, the encyclical of Pope Pius XI that instituted the feast day in 1925, and remembering that this institution's purpose sounded more in political theology than in personal piety and devotion.  This feast is a reminder that government is not all, that there are things which are not Caesar's, and that everything, in the end, is "under God."  A bit:

"[T]he Church, founded by Christ as a perfect society, has a natural and inalienable right to perfect freedom and immunity from the power of the state; and that in fulfilling the task committed to her by God of teaching, ruling, and guiding to eternal bliss those who belong to the kingdom of Christ, she cannot be subject to any external power."

This is, to put it mildly, a striking proposal.
