“Did God Really Say?” Part 1.

By |2026-05-26T12:15:03+00:00May 26th, 2026|Theology|

Or how I became a "Catholic Fundamentalist." In 2024, I gave a talk at a women's conference at a traditional Catholic parish called My Two Conversions.  I explained how in high school, I was a pretty liberal Catholic who worked at The Catholic Worker Soup Kitchen in the afternoons.  Perhaps in the evening, I might be found at a downtown Denver coffee-shop writing letters against the death penalty for Amnesty International. But, at 16 years old, I had a big conversion and I came to believe that Christ was truly present in the Blessed Sacrament.  Then, another 16 years later (several years after ordination, in fact) I became a traditional [...]

Predestination: Calvinism vs. Catholicism.

By |2026-05-16T18:27:18+00:00May 21st, 2026|Theology|

The top left is John Calvin, the theological father of modern Presbyterianism who believed in Double-Predestination (the notion that God creates some people for heaven and God creates others for hell.)   The top right is St. Francis De Sales, a Catholic saint and doctor of the Church.  Both said a lot about pre-destination. Granted, we Catholics have some Church Fathers who seemed to have flirted with Double Pre-Destination even before John Calvin did, so it's not a clear-cut topic.  But ultimately, St. Francis De Sales navigated the true way between the Fathers and Common-Sense on God's mercy.  Fr. Ludwig Ott has a book titled Fundamentals of Catholic Dogma in [...]

Bonum Ex Integra Causa.

By |2026-05-19T01:00:07+00:00May 19th, 2026|Theology|

Bonum ex integra causa, malum ex quocumque defectu is Latin for "Goodness comes from a complete cause, evil from any defect whatsoever." You may remember the free catechetical series I produced called Catechism of Pius X (CPX) which is a YouTube playlist at that link.  If you're converting to Apostolic Catholicism (either from Protestantism or modernism) I highly suggest you watch that series.  On CPX, I explained the traditional Catholic faith in about 20 hours.   Also online, I'm currently teaching the Roman Catechism of Trent (RCT.) It is also a YouTube playlist at that link.  Unlike CPX, we have not yet come to the end of RCT. As you [...]

Who Showed Up to Vatican II? Who Didn’t?

By |2026-05-20T00:24:56+00:00May 13th, 2026|Theology|

My favorite assignment as a parish priest began in 2017 when I was on-loan to the diocese of St. Augustine in Florida.  I lived and offered the Traditional Latin Mass at the Cathedral Basilica of the Immaculate Conception in downtown Jacksonville.  The families who attended my Mass loved not only the Mass, but also the Catholic faith.  After Mass, a surprising amount of families would come to the basement of the Cathedral to talk to each other and attend my classes on how to use all the tassels of the layman's Missal for the old Mass.  I came to know many of these families.  They loved God, the faith, their [...]

Three Ages of Martyrs.

By |2026-05-06T18:47:03+00:00May 7th, 2026|Theology|

The men of that [last] generation will have no deeds whatever, but there will come upon them temptation, and those who are worthy in this temptation will be higher than us and our fathers.—St. Ischyrion of Egypt, early Desert Father. Recently, I was thumbing through my friend’s Saint Andrew Daily Missal. The middle of that layman’s missal has a surprising history of the Catholic Church’s saints and martyrs. It describes the early Church saints in these shocking terms: “With very few exceptions, such as St. Gregory the Wonderworker (November 17th), St. Mary Magdalene (July 22nd), St. Martha (July 29th) and St. Petronilla (May 31st) the saints of the first four [...]

Suppressed Feasts from the Old Roman Missal.

By |2026-05-01T16:30:48+00:00May 5th, 2026|Updates|

While visiting some new friends, they brought me to an old chapel in the woods (seen above.) On their altar was a Roman Missal published around 1900.  As I was thumbing through it, I was amazed at numerous feasts that are now suppressed.  I snapped several pictures of these optional feasts. In writing the below article about them, I am not saying the Holy Spirit has been inactive on earth since the 1950s.  But I am saying these beautiful liturgical propers should probably be put back on our Roman calendar by a future Pope, at least granting the priest a possibility of using them as optional propers. Above is the [...]
