763. Faith is divided into explicit and implicit, according as the object believed is unfolded or not to the mind. (a) Faith is explicit regarding any truth, when assent is given to that truth as known in itself and expressed in terms proper to itself. Example: He has explicit faith in the Eucharist who has been instructed concerning the meaning of the mystery, and who assents to it according to that distinct knowledge. (b) Faith is implicit regarding any truth, when that truth is not known or not accepted in itself, but is accepted in another truth. Example: He has implicit faith in the Eucharist who has not yet heard of it, but who accepts all the teachings of the Church, even those he does not know. 764. Faith is implicit as follows: (a) Improperly, faith is implicit, if one does not give assent, but is prepared to give it, if necessary, or wishes to give it. These pious dispositions are not the act of faith itself, but they are its beginnings, or preparations leading up to it; they are good, but not sufficient. Example: A pagan who says he would accept the Christian creed, if he thought it were true, or who wishes that he could believe it. (b) Properly, faith is implicit, if one gives assent to a truth by accepting another in which it is contained, as a particular is contained in a universal (e.g., he who explicitly accepts all the truths of Christianity, implicitly accepts the Eucharist, even when in good faith he thinks it is not revealed), or as an instrument is involved in its principal cause (e.g., he who explicitly believes in the Redemption implicity believes in Baptism, which is the instrument by which Redemption is applied), or as means are contained in their end (e.g., he who explicitly believes that eternal life is a reward, implicitly believes that good works must be performed as a means to that end), or as the reality is expressed in the figure (e.g., those in the Old Testament who explicitly believed in the Paschal Lamb, implicitly believed in the sacrifice of Christ of which the Paschal Lamb was the figure), or as the assent of the disciple is bound up with the assent of the teacher (e.g., the child who explicitly accepts as true the doctrines of faith taught by his pastor, implicitly believes the sense and implications contained in the latter’s instructions). 765. The points about which explicit faith is required can be reduced to four heads (see Catechism of the Council of Trent). These heads are: (a) The things to be believed: “Preach the Gospel to every creature. He that believeth shall be saved” (Mark, xvi. 15). The Gospel doctrine is summarized in the Apostles’ Creed; (b) The things to be done: “Teach them to observe all things whatsoever I have commanded you” (Matt., xxviii. 20). The Ten Commandments (see Vol. II) are called the epitome of the whole law;
