5. There is a kind of humility which is of counsel and of perfection such as that which desires and seeks the contempt of others; but there is also a humility which is of necessity and of precept, without which, says Christ, we cannot enter into the kingdom of Heaven: "Thou shalt not enter into the kingdom of Heaven." [Matt. xviii, 3] And this consists in not esteeming ourselves and in not wishing to be esteemed by others above what we really are.

No one can deny this truth, that humility is essential to all those who wish to be saved. "No one reaches the kingdom of Heaven except by humility," says St. Augustine. [Lib. de Salut. cap. xxxii]

But, I ask, what is practically this humility which is so necessary? When we are told that faith and hope are necessary, it is also explained to us what we are to believe and to hope. In like manner, when humility is said to be necessary, in what should its practice consist except in the lowest opinion of ourselves? It is in this moral sense that the humility of the heart has been explained by the fathers of the Church. But can I say with truth that I possess this humility which I recognize as necessary and obligatory? What care or solicitude do I display to acquire it? When a virtue is of precept, so is its practice also, as St. Thomas teaches. And therefore, as there is a humility which is of precept, "it has its rule in the mind, viz., that one is not to esteem oneself to be above that which one really is." [22, quo xvi, 2, art. 6]

How and when do I practice its acts, acknowledging and confessing my unworthiness before God? The following was the frequent prayer of St. Augustine, "Noscam Te, noscam me-----May I know Thee; may I know myself!" and by this prayer he asked for humility, which is nothing else but a true knowledge of God and of oneself. To confess that God is what He is, the Omnipotent, "Great is the Lord, and exceedingly to be praised," [Ps. xlvii, 1] and to declare that we are but nothingness before Him: "My substance is as nothing before Thee" [Ps. xxxviii, 6]-----this is to be humble.
