8. Suspicion is permissible when it has for its aim measures of just prudence; charity forbids gratuitously malevolent thoughts, but not vigilance and precaution. 9. Suspicion is not only permissible, but it is at times an important duty for those who are charged with the direction and guardianship of others. Thus it is a positive obligation for a father in regard to his children, and for a master in regard to his servants, whenever there is occasion to correct some vice they know exists, or to prevent some fault they have reasonable cause to fear. 10. As to simple mistrust, which should not be confused with suspicion, it is only an involuntary and purely passive condition, to which we may be more or less inclined by our natural disposition without our free-will being at all involved. Mistrust, suspicion, rash judgment are then three distinct and very different things, and we should be careful not to confound them. XIX. ZEAL. But if you have bitter zeal, and there be contentions in your heart, glory not, and be not liars against the truth: for this is not wisdom descending from above, but earthly, sensual, diabolical. (St. James, Cath. Ep., c. III, vv. 14 and 15.) For the anger of man worketh not the justice of God. (St. James, Cath. Ep., c. I., v. 20.) 1. Zeal for the salvation of souls is a sublime virtue, and yet how many errors and sins are every day committed in its name! Evil is never done more effectually and with greater security, says Saint Francis de Sales, than when one does it believing he is working for the glory of God. 2. The saints themselves can be mistaken in this delicate matter. We see a proof of this in the incident related of the Apostles Saint James and Saint John; for our Lord reprimanded them for asking Him to cause fire from heaven to fall upon the Samaritans.[20] 3. Acts of zeal are like coins the stamp upon which it is necessary to examine attentively, as there are more counterfeits than good ones. Zeal to be pure should be accompanied with very great humility, for it is of all virtues the one into which self-love most easily glides. When it does so, zeal is apt to become imprudent, presumptuous, unjust, bitter. Let us consider these characteristics in detail, viewing them, for the sake of greater clearness, in their practical bearings. 4. In every home there grows some thorn, something, in other words, that needs correction; for the best soil is seldom without its noxious weed. Imprudent zeal, by seeking awkwardly to pluck out the thorn, often succeeds only in plunging it farther in, thus rendering the wound deeper and more painful. In such a case it is essential to act with reflection and great prudence. There is a time to speak and a time to be silent, says the Holy Spirit.[21] Prudent zeal is silent when it realizes that to be so is less hurtful than to speak.
