41 Everybody knows what difficulties the Church is experiencing in many parts of the world; with what lies, detraction and spoliation she has to contend. All know that in many places pastors of souls are either unhappily banished or thrown into prison without just cause, or else are so harassed that they are unable to carry out their duties properly. Finally, all are well aware that in those same places they are not allowed to have their own schools and training colleges, that they cannot publicly teach, defend or propagate Christian doctrine in periodicals or commentaries, and cannot properly train the youth in accordance with the same doctrine.
