(g) If a probable opinion for liberty is opposed by an opinion that is less, equally or more probable, one is free to act according to the principles of Probabiliorism, Equiprobabilism, Probabilism or Compensationism, according to conviction. 741. As for the use of moral systems by confessors, the two following rules are generally admitted: (a) If a penitent has formed his conscience according to one moral system, the confessor has no right to impose on him the opinion of a different moral system; for the Church allows liberty. (b) If a penitent has not formed his conscience according to any moral system and seeks the answer to a moral doubt, the confessor should decide, not necessarily for what his own system declares lawful, but for what appears, all the circumstances being considered, to be most advantageous spiritually for the penitent. Example: Fr. Titus is a Probabilist, and he usually advises questioners to follow opinions that are less probable; while Fr. Caius, who is a Probabiliorist, always requires that such persons follow the more probable opinions. Both act unwisely. For persons who are better disposed, it will often be more profitable to follow what is more probable or favorable to obligation; for those Whose dispositions are less good, milder opinions may be recommended, lest the smoking flax of goodness that is in them be entirely extinguished. Neither is it right to impose as certain an obligation which the penitent, if he were acquainted with Moral Theology, would see is controverted. 742. In case of disagreement between confessor and penitent as to whether absolution may be given, whose opinion should prevail? (a) If the disagreement is concerned with matters about which the confessor himself has to judge (e.g., the disposition of the penitent, the requisite matter for absolution, etc.), the opinion of the confessor must prevail; for the act of judging is his own, and he must be guided therefore by his own conviction. (b) If the disagreement is concerned with matters about which the confessor is not the judge (such as the controversies of schools and theologians), the confessor may not refuse absolution to a well-disposed penitent, just because the latter will not accept the opinion of his school or system. If it be manifest that the penitent’s opinion is false or improbable, absolution may be denied him, unless it seems more prudent to leave him in good faith. PART II SPECIAL MORAL THEOLOGY 743. In the First Part of this work, the means to man’s Last End were spoken of in a general way; the features that are common to all good acts--that they be human, morally deserving, directed according to law and conscience--were treated. In the present Part the means to the Last End will be discussed in particular, and we shall consider in turn the kinds of duties that are owed by all men and those owed by persons in special states of life.
