Republished here for the first time in nearly a century, coincidentally in the wake of another encyclical, not to mention a new universal catechism, both tending to promote a centralized and hierarchical - medieval in Tyrrell’s phraseology - view of the Church, it is bound to strike the reader in an astonishingly prophetic book. To read it is to realize that, whatever else it may be, it is neither minor nor ephemeral. The issues it treats are still large and live in the Church.
