paste, the whole body, the whole flock, burn, perish, rot, die. Arius was but one spark in Alexandria, but as that spark was not at once put out, the whole earth was laid waste by its flame." (ST II:II 11:3 corpus)According to Michael Novak, Aquinas' view in the matter of death penalty for obstinate heretics is one of the more difficult parts of dealing with Thomism. Forced baptism of children of Jews and heretics The position taken by Aquinas is that if children were being reared in error, the Church had no authority to intervene. From Summa Theologica II-II Q. 10 Art. 12: Injustice should be done to no man. Now it would be an injustice to Jews if their children were to be baptized against their will, since they would lose the rights of parental authority over their children as soon as these were Christians. Therefore these should not be baptized against their parent's will. The custom of the Church has been given very great authority and ought to be jealously observed in all things, since the very doctrine of Catholic Doctors derives its authority from the Church. Hence we ought to abide by the authority of the Church rather than that of an Augustine or a Jerome or any doctor whatever. Now it was never the custom of the Church to baptize the children of Jews against the will of their parents. There are two reasons for this custom. One is on account of the danger to faith. For children baptized before coming into the use of reason, might easily be persuaded by their parents to renounce what they had unknowingly embraced; and this would be detrimental to the faith. The other reason is that it is against natural justice. For a child is by nature part of its father: at first, it is not distinct from its parents as to its body, so long as it is enfolded within the mother's womb and later on after birth, and before it has the use of free will, it is enfolded in the care of its parents, like a spiritual womb. So long as a man does not have the use of reason, he is no different from an irrational animal. Hence, it would be contrary to natural justice, if a child, before coming to the use of reason, were to be taken away from its parent's custody, or
