Traditional Liberalism

This article is pretty amazing, and I will be thinking about the implications of it for a while. If I understand it correctly, it is pessimistic about any attempt to translate a traditional Catholic position into secular language in an attempt to make a convincing case for anyone entrenched in the "liberal tradition." Rather, we should just boldly live out our Christian lives in the fullness of the Catholic tradition, confronting the insanity of our secular culture with an alternative full of the truth, goodness, and beauty of God. It made me think of this passage from Isaiah 2:2-4 that I've been studying:

It shall come to pass in the latter days
that the mountain of the house of the LORD
shall be established as the highest of the mountains,
and shall be raised above the hills;
and all the nations shall flow to it,
and many peoples shall come, and say:
"Come, let us go up to the mountain of the LORD,
to the house of the God of Jacob;
that he may teach us his ways
and that we may walk in his paths."
For out of Zion shall go forth the law,
and the word of the LORD from Jerusalem.
He shall judge between the nations,
and shall decide for many peoples;
and they shall beat their swords into plowshares,
and their spears into pruning hooks;
nation shall not lift up sword against nation,
neither shall they learn war any more.
