Saint Augustine, The City of God, Vol. II

with those who weep, having fights without, fears within, desiring to be dissolved and to be with Christ, wishing to see the Romans that he might have some fruit among them as among the other Gentiles, envying the Corinthians and by that very envy fearing lest their minds be seduced from the chastity which is in Christ, having great sadness and continual sorrow of heart regarding the Israelites, because they, being ignorant of the justice of God and wishing to establish their own, were not subject to the justice of God; and not only sorrow, but even proclaiming his mourning to certain ones who had sinned before and had not done penance for their uncleanness and fornications.

If these movements, these affections coming from the love of the good and from holy charity are to be called vices, let us allow that those things which are truly vices be called virtues. But when these affections follow right reason, when they are applied where they ought to be, who then would dare to call them diseases or vicious passions? For this reason, the Lord Himself, in the form of a servant, deigned to live a human life, but, having no sin at all, He applied them where He judged they ought to be applied. For in Him, in whom there was a true human body and a true human soul, human affection was not false. Therefore, when these things are recounted in the Gospel, that He was grieved with anger over the hardness of the heart of the Jews, that He said: I rejoice for your sakes, that you may believe, that He shed tears when about to raise Lazarus, that He desired to eat the Passover with His disciples, that His soul was sad when His passion was approaching: they are surely not reported falsely. But He undertook these movements with a human soul by the grace of a certain dispensation, just as He became man when He willed.
