SECT. 30.—DEFINITIONS AND JUDICIAL DECISIONS CONSIDERED GENERALLY
The chief rules of Catholic belief are the definitions and decisions of the Church. Before we study them in detail, it will be well to treat of the elements and forms more or less common to them all.
I. Definitions and decisions are essentially acts of the teaching power, in the strictest sense of the word; acts whereby the holder of this power lays down authoritatively what his subjects are bound to accept as Catholic doctrine or reject as anti-Catholic. Hence, as distinguished from other acts of the Teaching Apostolate, they are termed decrees, statutes, constitutions, definitions, decisions concerning the Faith. In the modern language of the Church, “Definition” means the positive and final decision in matters of Faith (dogmas), and “Judgment” means the negative decision whereby false doctrines are condemned (censures). The wording of definitions is not restricted to any particular form. Sometimes they take the form of a profession of Faith: “The Holy Synod believeth and confesseth;” at other times they take the form of a declaration of doctrine, as in the “chapters” of the Council of Trent and the Vatican Council, or of canons threatening with “anathema” all who refuse to accept the Church’s teaching.
II. The general object of authoritative decisions in doctrinal matters is to propose dogmas in clear and distinct form to the Faithful, and thereby to promote the glory of God, the salvation of souls, and the welfare of the Church. Sometimes, however, there are certain specific objects; e.g., (1) to remove existing doubts. The definitions of the Immaculate Conception and the Infallibility of the Pope are cases in point. (2) To condemn criminal doubts prevailing against dogmas already defined, e.g. the case of the five propositions of Jansenius. (3) To prevent future doubts and to confirm the Faith of the weak. In this case, as in the preceding, the new definition takes the form of a confirmation or renewal of a former definition. Thus the Vatican Council, at the end of its first constitution,
