On the question why certain Names in the Holy Scriptures are changed (226-230)

But will you impose any such injunctions as these on your own son? Unless you treat your servants with gentleness, do not treat those of the same rank as yourself socially. Unless you behave decorously to your wife, never bear yourself respectfully to your parents. If you neglect your father and your mother, be impious also towards God. If you delight in pleasure, you must not keep aloof from covetousness. Do you desire great riches? Then be also eager for vain-glory.

For what more need we add? Need you not desire to be moderate in some things unless you are able to be so in all? Would not your son say to you in such a case, My father, what do you mean? Do you wish your son to become either perfectly good or perfectly bad, and will you not be content if he keeps the middle path between the two extremes?

Was it not for this reason that Abraham also, at the time of the destruction of Sodom, began at fifty and ended at ten? [*] Therefore, propitiating and supplicating God, entreat him that if there could not be found among his creatures a complete remission so as to give them liberty, of which the sacred number of fifty is a symbol, at least the intermediate instruction which is equal in number to the decade, might be accepted for the sake of the deliverance of the soul which was about to be condemned.

But those who are instructed have many more opportunities of prayer than those who are destitute of teachers, and those who are well initiated in encyclical [*] [*]

And it is something like this that Esau seems to have said to his father, "Have you not one blessing for me, O my father? Bless me, bless me, also, O my father!" [*] For different blessings have been set apart for different persons, perfect blessings for the perfect, and moderate blessings for the imperfect. As is the case also with bodies; for there are different exercises appropriate to those which are in health, and to those which are sick. And also different regimens of food, and different systems of living, and not the same. But some things are suitable to the one kind that they may not become at all diseased; and other things are good for the other sort, that they may be changed and rendered more healthy.
