(b) The reason for rejecting the command may be the one who gave the command, considered as a private individual. As the Pope in his personal relations is not above human weakness, he may be swayed by hatred, prejudice or impulsiveness in issuing commands to or forming judgments about individual subjects. Hence, if we suppose that it is reasonably certain that a Pope is unfavorable to an individual, and that the latter accordingly is unwilling to have a case in which he is concerned fall under the immediate decision of that Pope, neither schism nor any other sin is committed; for it is natural that the person should wish to protect his own interests against unfairness.
(c) The reason for rejecting the Pope’s judgment may be the one who gave the command considered in his official capacity as Pope. In this case the person is guilty of schism, since he disobeys, not because the thing ordered is difficult or because he fears that the individual will be unjust, but because he does not wish to recognize the authority of Pope in him who issued the judgment.
1370. Comparison of Heresy and Schism.—(a) These sins are not the same, since heresy is opposed to faith, schism to charity. A person who really believes that the Church is one in its head and its body, may nevertheless out of pride, hatred, ambition, interest, self-sufficiency, etc., decide not to recognize the authority of the head, or not to communicate with the body. (b) There is an intimate union between heresy and schism, since every heretic separates himself from the unity of faith, while schism is always found to adopt some heresy as a justification for its separation (I Tim., i. 6). Thus, the Eastern Schism soon trumped up charges of heresy against the Church, and history shows that schism almost invariably leads to a denial of papal primacy.
1371. The Opposition between Schism and Charity.—(a) Charity in itself is a spiritual bond of unity between the soul and God, for love is unitive. One who sins against this unity by offending God or his neighbor, is not thereby a schismatic, since one may hate an individual, for example, without hating the Church. (b) Charity in its effect is the communion of all the faithful in one mystical body of Christ, for charity inspires the desire to love, not only individuals, but also the spiritual society formed of individuals in the entire world. One who sins against the unity and peace of the Church is a schismatic.
1372. The Sinfulness of Schism.—(a) Schism has a special seriousness, since it is opposed to the union and peace of mankind as a whole in the universal spiritual society which is the Church. It seems to be the greatest sin against the neighbor; for other sins are against the individual or against the multitude in temporal things, while this sin is against the multitude and in spiritual things. Scripture (cfr. I Cor., i. 10) and Tradition (e.g., St. Clement of Rome, St. Ignatius of Antioch, St. Irenaeus, St. Cyprian, St. Augustine) energetically condemn the sin of schism.
(b) Objectively, it is not as serious as unbelief, since unbelief is against God, schism against the neighbor; but subjectively, or in its consequences, it may be greater than unbelief, as when a schismatic sins with greater contempt than an unbeliever, or is an occasion of more danger to others.
1373. Schism, like heresy, may be either formal or material (see 828). (a) Formal schism is that described above, in which one wishes to separate oneself from the unity of the Church, and is in culpable revolt. It is a mortal sin. (b) Material schism is that in which one is in fact separated from the unity of the Church, but is in good faith. An example is the Great Schism of the West (1378-1417), when there were rival claimants for the Papacy, and invincible ignorance among the people as to who was the true head. This kind of schism is not a mortal sin.
1374. The Spiritual Powers of Schismatics.—(a) The power of Orders is not lost through schism, for that power is conferred through a consecration, and the consecrations of the Church are permanent. Hence, a schismatical priest can perform validly the acts that pertain to the power of Orders, such as the celebration of Mass and administration of the Sacraments; but he does not perform those acts lawfully, unless the Church permits, for the power of Orders should not be used by an inferior except as permitted by the superior.
(b) The power of jurisdiction may be lost through schism, for that power depends on a commission received from a superior, which may be withdrawn by him. Hence, a schismatical priest deprived of jurisdiction could not absolve, excommunicate, grant indulgences, or perform other acts that pertain to the power of jurisdiction.
1375. The law of the church on the powers of schismatics is as follows:
