Chapter 1 — Preface to the Roman Catechism
Section 22. Study Of The Word Of God — Now all the doctrines in which the faithful are to be instructed are contained in the Word of God, which is found in Scripture and tradition. To the study of these, therefore, the pastor should devote his days and his nights, keeping in mind the admonition of St. Paul to Timothy, which all who have the care of souls should consider as addressed to themselves: Attend to reading, to exhortation, and to doctrine, for all Scripture divinely inspired is profitable to teach, to reprove, to correct, to instruct injustice, that the man of God may be perfect, furnished to every good work.
