 On questions relating to the coercion of heretics and unbelievers, Thomas supports the practice of the medieval Church. A heretic (i.e., someone who has been baptised as a Catholic but has since rejected orthodox Catholic doctrine) can rightly be compelled to return to the Church, but a Jew or unbeliever who has never been a Catholic should not be converted by force  (Summa, 2–2, q. 10, a. 8).  Simple people should not be exposed to the opinions of unbelievers  (Summa, 2–2, q. 10, a. 7, 9).  The children of Jews should not be taken from them and brought up as Catholics, since this would violate natural justice, which gives parents control over under-age children  (Summa, 2–2, q. 10, a. 12).  The religious rites of Jews may be tolerated, but not those of other unbelievers, except to avoid strife or in hope of their gradual conversion  (Summa, 2–2, q. 10, a. 11).
