There are two vices opposed to this liberty of spirit,—instability and constraint, or dissipation and servility. The former is a certain excess of freedom which causes us to change our devout exercises or state of life without reason and without knowing if it be God’s will. On the slightest pretext practices, plans and rules are altered and for every trivial obstacle our laudable customs are abandoned. In this way the heart is dissipated and spent and becomes like an orchard open on all sides, the fruit whereof is not for the owner but for the passers-by. Constraint or servility is a certain lack of liberty owing to which the mind is overwhelmed with vexation or anger when we cannot carry out our designs, even though we might be doing something better. For example: I resolve to make a meditation every morning. Now if I have the spirit of instability or dissipation I am apt to defer it until evening for the most insignificant reason,—because I was kept awake by the barking of a dog, or because I have a letter to write, although it be not at all pressing. If on the contrary I have the spirit of constraint or servility I will not give up my meditation even though a sick person has great need of my aid just then, or if I have an important and urgent dispatch to send which should not be deferred; and so on. It remains for me to give you some examples of true liberty of spirit which will make you understand it better than I can explain it. But, before doing so, it is well that I should say there are two rules which it is necessary to observe in order not to make any mistake on the subject. The first is that a person must never abandon his pious practices and the common rules of virtue unless it is plainly evident that God wills that he do so. Now this will is manifested in two ways,—through necessity and through charity. I desire to preach this Lent in some little corner of my diocese; however, if I get sick or break my leg I need not give way to regret or inquietude because I cannot do as I intended, for it is evident that it is the will of God that I serve Him by suffering and not by preaching. Or, even if I am not ill or crippled, but an occasion presents itself of going to some other place which if I do not avail myself of the people there may become Huguenots, the will of God is sufficiently manifest to make me amiably change my plans. The second rule is that when it is necessary to make use of this liberty of spirit from motives of charity, care should be taken that it is done without scandal or injustice. For instance: I may know that I should be more useful in some distant place not within my own diocese: I should have no freedom of choice in this matter for my obligations are here and I should give scandal and do an injustice by abandoning my charge.
