De Instituto · Who We Are

“Tradidi enim vobis in primis quod et accepi…”

1 Corinthians 15:3

The Mary Michael Machabee Institute exists for a single purpose: that the whole doctrine of the Catholic Church be known, loved, and lived by the faithful the world over.

We believe the troubles of the last century trace to a single root — forgotten doctrine — and we labor to return that inheritance, whole and undimmed, to the hearts and minds of Catholics in every walk of life.
