Pope Pius XI, Iniquis Afflictisque & Mexico

I recently read the encyclical letter of Pope Pius XI, Iniquis Afflictisque of 1926, on the persecution of the Church in Mexico. Viva Cristo Rey!

It is an excellent and instructive read, not only on the situation in Mexico at that time, but on certain general Church-State principles.
