823. Since error is not consistent, false teachings are found that accept all the above-mentioned degrees of unbelief, or borrow impartially from all.
(a) Indifferentism or Latitudinarianism holds that all forms of religion are equally true, and that it makes no difference whether one is Buddhist, Jew or Christian. In a modified form, Indifferentism teaches that any form of Christian belief, provided it suits the inclinations of the individual concerned, may be followed, and hence it is left to each one to decide whether he prefers Catholicism or one of the bodies of the Orthodox Church or of Protestantism. Many who profess a denominational creed or confession are Indifferentists in belief.
(b) Syncretism holds that there are truths in all separate religions, but that none of them has all the truth, and hence that one must select what is good from each, rejecting the evil. Thus, the Judaizers of the first century borrowed from Judaism, the Gnostics and Manicheans from paganism, while today Freemasonry, Theosophy, Christian Science and Spiritism accept, along with the Gospel, ancient pagan, Buddhistic, Brahmanistic and Mohammedan theories; finally, Mormonism endeavors to unite characteristics of the Old and the New Testament dispensations. In a restricted form, religious Syncretism teaches the doctrine of Pan-Christianism—that is, that truth is scattered among the various Christian denominations, and that all should confederate as equals on the basis of more important doctrines to be agreed on by all.
824. What is the order of gravity in unbelief, as between infidelity, Judaism, heresy?
(a) The gravity of a sin against faith is to be determined primarily from the subjective resistance made to faith, so that he sins more against the light to whom greater light was given. The sin of unbelief in one who has received the Gospel (heresy), is greater than the same sin in one who has accepted only the Old Testament (Judaism); in one who has received the revelation of the Old Testament (Judaism) the sin of unbelief is more serious than the same sin in one who has not received that revelation (infidelity).
(b) The gravity of unbelief is measured secondarily from the objective opposition of error to truth, so that he is farther away from faith who is farther away from Christ and the Gospel. Thus, a Buddhist denies Christian truths more radically than a Jew, and a Jew more radically than a Protestant. Hence, of three apostates, one to Protestantism, another to Judaism and a third to Buddhism, the second sins more grievously than the first, the third more grievously than the second.
825. If we leave out of consideration the radical truth of divine revelation (formal object of faith), it is possible that a heretic, in spite of his acceptance of Christ and the scriptures, should be farther away objectively from faith than an infidel—that is, that he should deny more revealed truths (material objects of faith). Thus, the Manicheans called themselves followers and disciples of Christ, but their teaching on God contains more errors than does the doctrine of many pagans.
826. Heresy.—Heresy is defined as “an error manifestly opposed to faith and assented to obstinately by one who had sincerely embraced the faith of Christ.”
(a) It is called “error,” that is, positive assent given to error, or dissent from truth. Hence, those who merely act or speak as if they do not believe, but who internally do believe, are not heretics, although in the external forum they may fall under the presumption of heresy. Similarly, those who have doubts or difficulties in matters of faith, but who do not allow these to sway their judgment, are not guilty of heresy, since they give no positive assent to error (see 842 sqq.). Examples: Titus is internally convinced of the truth of the Church’s teaching; but he attends Protestant services, says he does not believe the Trinity, refuses to make a profession of faith required by the Church, separates himself from obedience to the authorities of the Church, and calls himself an independent. By his former external acts he makes himself guilty of disobedience and falls under the suspicion of heresy, and by his last external act he incurs the guilt of schism; but, since internally he does not disbelieve, he is not a heretic. Balbus has doubts before his mind from his reading or conversation, but he must immediately give his whole attention to a very pressing matter of business, and so gives neither assent nor dissent to the doubts. He is not guilty of heresy, since he formed no positive erroneous judgment.
(b) Heresy is “opposed to faith.” By faith here is understood divine faith, especially divine and Catholic faith (see 755). Hence, an error opposed to what one held to be a genuine private revelation, or to the public revelation, especially when dogmatically defined by the Church, is heretical. On the contrary, an error opposed to ecclesiastical faith alone, to human faith, or to human science, is not of itself heretical. Examples: The Saints who received special private revelations from Christ with proofs of their genuineness would have been guilty of heresy, had they refused to believe. Sempronius refuses to believe some Biblical teachings about things not pertaining to faith and morals and not expressly defined by the Church (e.g., chronological, physical, geographical, statistical data). If he really believes that what he denies is contained in the Bible, he is guilty of heresy. Balbus admits the infallibility and authority of the Church, but he does not believe that a certain Saint solemnly canonized is in heaven, that a certain non-infallible decision of a Roman Congregation is true, that certain second lessons of the Breviary or certain relics are genuine. He is not a heretic, since, as supposed, he denies no revealed truth; but in his first unbelief he sins against ecclesiastical faith; in his second unbelief, if the contrary of the decision has not been clearly established, he sins against the duty of religious assent; in his third unbelief, he sins against prudence, if he has no good grounds for his opinion, or against the respect due the Church, if he is moved by contempt for its judgment. In a conversation between A, B, C, D and E, the following opinions are defended. A thinks that any use of natural knowledge with reference to matters of faith is wrong; B, that the theologian should employ mathematics and physical science, but avoid reasoning and philosophy; C, that the method and principles of Scholasticism are not suited to our ago or to all peoples; D, that the psychology and cosmology of the Scholastics should be remade entirely; E, that many hypotheses of Aristotle in physics have been proved false. The opinion of A contains heresies condemned in the Vatican Council regarding the preambles of faith and the motives of credibility. The opinions of B and C are at least contrary to the religious assent due the authority of the Church (see Denzinger, Enchiridion, nn. 1652, 1680, 1713, Code of Canon Law, Canon 1366, Sec.2, _Humani Generis_, n. 11-14). The opinion of D, as it stands, contains a denial of several doctrines of faith, such as the immortality of the soul and the creation of the world, and is thus implicitly heretical. The opinion of E is true and admitted by all.
