Moreover, we do not raise any objection to their religion on the ground of the difference between the institutions appointed by Numa Pompilius for the worship of the gods by the Romans, and those which were up till that time practised in Rome or in other parts of Italy; nor on the fact that in the age of Pythagoras that system of philosophy became generally adopted which up to that time had no existence, or lay concealed, perhaps, among a very small number whose views were the same, but whose religious practice and worship was different: the question upon which we join issue with them is, whether these gods were true gods, or worthy of worship, and whether that philosophy was fitted to promote the salvation of the souls of men. This is what we insist upon discussing; and in discussing it we pluck up their sophistries by the root. Let them, therefore, desist from bringing against us objections which are of equal force against every sect, and against religion of every name. For since, as they admit, the ages of the world do not roll on under the dominion of chance, but are controlled by divine Providence, what may be fitting and expedient in each successive age transcends the range of human understanding, and is determined by the same wisdom by which Providence cares for the universe.
