The religion of souls should follow the law of development of bodies. Though bodies develop and unfold their component parts with the passing of the years, they always remain what they were. There is a great difference between the flower of childhood and the maturity of age, but those who become old are the very same people who were once young. Though the condition and appearance of one and the same individual may change, it is one and the same nature, one and the same person. The tiny members of unweaned children and the grown members of young men are still the same members.
Men have the same number of limbs as children.
If, however, the human form were to turn into some shape that did not belong to its own nature, or even if something were added to the sum of its members or subtracted from it, the whole body would necessarily perish or become grotesque or at least be enfeebled. In the same way, the doctrine of the Christian religion should properly follow these laws of development, that is, by becoming firmer over the years, more ample in the course of time, more exalted as it advances in age. In ancient times our ancestors sowed the good seed in the harvest field of the Church. It would be very wrong and unfitting if we, their descendants, were to reap, not the genuine wheat of truth but the intrusive growth of error. Saint Vincent of Lerins was a priest monk who lived on the island of Lerins during the fifth century.
