It is most of all fundamental that they should have an attitude of mind that is worthy of their faith; one that is not nervous or apologetic for the Church, not anxious about the Pope lest he should "interfere too much," nor frightened of what the world may say.

They should have an unperturbed conviction that the Church will have the last word in any controversy, and that she has nothing to be alarmed at, though all the battalions of newest thought should be set in array against her; they should be lovingly proud of the Church, and keep their belief in her at all times joyous, assured, and unafraid.
Theology is not for them, neither required nor obtainable, though some have been found enterprising enough to undertake to read the _Summa_, and naive enough to suppose that they would be theologians at the end of it, and even at the outset ready to exchange ideas with Doctors of Divinity on efficacious grace, and to have "views" on the authorship of the Sacred Writings.
