If, as is said, peace of mind is perfect health, and zeal is opposed to peace, then a person stirred by zeal is ill with a grievous sickness.
While you presume to stir up your zeal against the sickness of others, you will have banished health from your own soul. You should concern yourself with your own healing. But if you wish to heal those who are sick, know that the sick have greater need of loving care than rebukes.
Zeal is not reckoned among mankind as a form of wisdom; rather it is one of the sicknesses of the soul, arising from narrow-mindedness and deep ignorance.
The beginning of divine wisdom is the serenity acquired from generosity of soul and forbearance with human infirmities.
For he says ‘You who are strong should bear the infirmities of the weak’ (Rom 15:1), and ‘Put right transgressor with a humble spirit’ (Gal 6:1). The Apostle numbers peace and long-suffering among the fruits of the Holy Spirit.
