754. The Object of Faith.—There is a twofold object of faith, viz., material and formal.
(a) The material object, or the truth that is believed, includes all that is contained in the Word of God, whether written or handed down by tradition. The principal material object is God Himself as the Deity, or Supreme Truth in Being (_prima veritas in essendo_); the secondary material object embraces all other revealed truths.
(b) The formal object of faith, or the motive that prompts one to give assent to the material object, is the authority of God, who is Supreme Truth in Knowing and Speaking (_prima veritas in cognoscendo et dicendo_), and hence He can neither be deceived nor deceive.
755. The material object of faith includes all truths revealed by God; but, since it belongs to the Church to teach those truths, there is a distinction of truths that are revealed by God but not defined by the Church, and truths that are revealed by God and defined by the Church as revealed. Thus: (a) divine faith is belief in revealed truth that has not been declared by the Church as revealed; (b) divine and Catholic faith is belief in a revealed truth that has been proposed as such by the Church, either solemnly or ordinarily. Example: Dogmas contained in creeds, definitions of Popes or general councils. The Vatican Council has determined the object of this faith: By divine and Catholic faith all those things must be believed which are contained in the written word of God and in tradition, and which are proposed by the Church, either by a solemn pronouncement or by her ordinary and universal magisterium, to be believed as divinely revealed (Ibid., Denz. 1792).
756. The formal object of faith extends to all truths that have been revealed and to no others. Theologians discuss the status of certain truths connected with revelation concerning which the Church is guaranteed infallibility on account of her teaching office. Special difficulties arise in relation to: a) dogmatic facts, that is, definitions concerning particular facts closely related to dogma (e.g., that Anglican orders are invalid; that a particular book contains a sense contrary to revelation; that this Supreme Pontiff, legitimately elected, is the successor of St. Peter in the primacy and consequently infallible); b) theological conclusions, that is, deductions drawn from revealed truth.
Many theologians teach that both dogmatic facts and theological conclusions when defined by the Church constitute a special object of faith distinct from divine and Catholic faith, namely, ecclesiastical faith. Accordingly, for them, ecclesiastical faith is the internal assent given to truths connected with revelation and defined by the Church as true, the motive of assent being the infallibility of the Church in her teaching office.
Others deny the existence of such faith and insist a) that dogmatic facts are contained in revealed doctrine implicitly as singulars in universals and hence are believed before definition by divine faith implicitly, and after definition by divine and Catholic faith, b) that theological conclusions before definition are held by theological assent, afterwards by divine and Catholic faith. Some also have maintained that before definition such conclusions belong to divine faith. (For a summary of the various teachings on this problem see Reginaldo-Maria Schultes, O.P., _Introductio in Historiam Dogmatum_, pp. 46 ff.; Marin-Sola, O.P., _L’Evolution homogene du Dogme Catholique_).
757. Private revelations, even when approved by the Church, are not an object of divine and Catholic faith, for they form no part of the revelation given to the whole human race that was closed with the death of the Apostles and committed to the Church. Hence: (a) if they are negatively approved by the Church, the approval means only that such revelations contain nothing contrary to faith and morals, and are useful and edifying; (b) if they are approved positively (as is the case with the revelations of St. Hildegarde, St. Brigit, and St. Catherine of Siena), the approval means that they appear to be true divine revelations and may be prudently accepted as such.
758. The assent to be given to private revelations, therefore, is as follows:
(a) Such revelations should receive the assent of divine faith, if it is certain that they are genuine. This applies to those to whom and for whom they were given, and probably to others also. It rarely happens, however, that the genuineness of a private revelation can be critically established, and the Church does not require that such revelations be accepted by all the faithful. To refuse assent, therefore, to a private revelation is not generally an offense against divine faith.
