On the Creation of Magistrates (1.51-1.55)

And he receives all persons of a similar character and disposition, whether they were originally born so, or whether they have become so through any change of conduct, having become better people, and as such entitled to be ranked in a superior class; approving of the one body because they have not defaced their nobility of birth, and of the other because they have thought fit to alter their lives so as to come over to nobleness of conduct. And these last he calls proselytes (προσηλύτους), from the fact of their having come over (προσεληλυθέναι) to a new and God-fearing constitution, learning to disregard the fabulous inventions of other nations, and clinging to unalloyed truth.

Accordingly, having given equal rank and honour to all those who come over, and having granted to them the same favours that were bestowed on the native Jews, he recommends those who are ennobled by truth not only to treat them with respect, but even with especial friendship and excessive benevolence. And is not this a reasonable recommendation? What he says is this. "Those men, who have left their country, and their friends, and their relations for the sake of virtue and holiness, ought [*]

Moreover, he also enjoins his people that, after they have given the proselytes an equal share in all their laws, and privileges, and immunities, on their forsaking the pride of their fathers and forefathers, they must not give a license to their jealous language and unbridled tongues, blaspheming those beings whom the other body looks upon as gods, lest the proselytes should be exasperated at such treatment, and in return utter impious language against the true and holy God; for from ignorance of the difference between them, and by reason of their having from their infancy learnt to look upon what was false as if it had been true, and having been bred up with it, they would be likely to err.

And there are some of the Gentiles, who, not attending to the honour due to the one God alone, deserve to be punished with extreme severity of punishment, as having forsaken the most important classification of piety and holiness, and as having chosen darkness in preference to the most brilliant light, and having rendered their own intellect blind when it might have seen clearly.

And it is well that a charge should be given to all those who have any admiration for virtue to inflict all such punishment out of hand without any delay, not bringing them before either any judgment seat, or any council, or any bench of magistrates, but giving vent to their own disposition which hates evil and loves God, so as to chastise the impious with implacable rigour, looking upon themselves as everything for the time being, counsellors, and judges, and generals, and members of the assembly, and accusers, and witnesses, and laws, and the people; that so, since there is no conceivable hindrance, they may with all their company put themselves forward fearlessly to fight as the champions of holiness.
