“Is there to be no development of religion in the Church of Christ? Certainly, there is to be development and on the largest scale.
Who can be so grudging to men, so full of hate for God, as to try to prevent it? But it must truly be development of the faith, not alteration of the faith. Development means that each thing expands to be itself, while alteration means that a thing is changed from one thing into another.
The understanding, knowledge and wisdom of one and all, of individuals as well as of the whole Church, ought then to make great and vigorous progress with the passing of the ages and the centuries, but only along its own line of development, that is, with the same doctrine, the same meaning and the same import.”
– from the first instruction by St. Vincent of Lerins, as found in today’s office of readings
