Clandestine Ordinations Against Church Law: Lessons from Cardinal Wojtyła and Cardinal Slipyj
One of the most remarkable episodes in the life of Karol Wojtyła—and one from which we can learn a great deal today—took place during his time as Cardinal of Kraków. It is astonishing to me that, with all the attention lavished …
The Rosary Sounds the Trumpet of the New Israel
When in your own land you go to war against an enemy that is attacking you, you shall sound the alarm on the trumpets, and the Lord, your God, will remember you and save you from your foes (Numbers 10:9). …
Angels: Fellow Worshipers in the Liturgy of Heaven

Lights and Shadows in the Pontificate of Pius XII
Back in May, I published an article at LifeSiteNews entitled “Coincidences during the reign of Pius XII? Political background to Vatican II and liturgical changes.” The article generated a fair amount of discussion, both favorable and critical. Since the pontificate …

Andrea Grillo: The Mind Behind the Motu Proprio
Andrea Grillo (born 1961) is a professor of Sacramental Theology and Philosophy of Religion at the Pontifical Athenaeum of St. Anselm in Rome (Sant’Anselmo) and of Liturgy in Padua at the Abbey of Santa Giustina. With the promulgation of Pope …

I once wrote an article for Rorate Caeli entitled “Conservative Fragility.” I have noticed in recent weeks the extent to which conservative Catholics are sounding jittery, short-tempered, dismissive, and intolerant towards traditionally-minded Catholics who refuse to embrace the papally-bestowed role …
