A man that is a heretic - Generally defined, one that is obstinately attached to an opinion contrary to the peace and comfort of society, and will neither submit to Scripture nor reason. Here it means a person who maintains Judaism in opposition to Christianity, or who insists on the necessity of circumcision, etc., in order to be saved. This is obviously the meaning of the word heretic in the only place in which it occurs in the sacred writings.

After the first and second admonition, reject - Labour to convince him of his error; but if he will not receive instruction, if he have shut his heart against conviction, then - burn him alive? No: even if demonstrably a heretic in any one sense of that word, and a disturber of the peace of the Church, God gives no man any other authority over him but to shun him, παραιτου. Do him no harm in body, soul, character, or substance; hold no communion with him; but leave him to God. See the notes on Acts 5:17; Acts 24:14 (note), where the word heresy is particularly explained.

Whether the Foreknowledge of Merits is the Cause of Predestination
Whether the Foreknowledge of Merits is the Cause of Predestination We proceed to the fifth article thus: 1. It seems that the foreknowledge of merits is the cause of predestination. For the apostle says: "whom he did foreknow, he also did predestinate" (Rom. 8:29), and the gloss of Ambrose on the words "I will have mercy on whom I will have mercy" (Rom. 9:15) says: "I will have mercy on whom I foreknow will return to me with his whole heart." It thus appears that the foreknowledge of merits is the …

Whether Isidore's Description of the Quality of Positive Law is Appropriate?
Objection 1: It would seem that Isidore's description of the quality of positive law is not appropriate, when he says (Etym. v, 21): "Law shall be virtuous, just, possible to nature, according to the custom of the country, suitable to place and time, necessary, useful; clearly expressed, lest by its obscurity it lead to misunderstanding; framed for no private benefit, but for the common good." Because he had previously expressed the quality of law in three conditions, saying that "law is anything …

Whether Human Law Should be Framed for the Community Rather than for the Individual?
Objection 1: It would seem that human law should be framed not for the community, but rather for the individual. For the Philosopher says (Ethic. v, 7) that "the legal just . . . includes all particular acts of legislation . . . and all those matters which are the subject of decrees," which are also individual matters, since decrees are framed about individual actions. Therefore law is framed not only for the community, but also for the individual. Objection 2: Further, law is the director of human …
