Pleading
We shall consider our text, then, as one of the productions of a great master in spiritual matters, and we will study it, praying all the while that God will help us to pray after the like fashion. In our text we have the soul of a successful pleader under four aspects: we view, first, the soul confessing: "I am poor and needy." You have next, the soul pleading, for he makes a plea out of his poor condition, and adds, "Make haste unto me, O God!" You see, thirdly, a soul in it's urgency, for he cries, …

Whether a Man May Merit Restoration after a Fall?
Objection 1: It would seem that anyone may merit for himself restoration after a fall. For what a man may justly ask of God, he may justly merit. Now nothing may more justly be besought of God than to be restored after a fall, as Augustine says [*Cf. Ennar. i super Ps. lxx.], according to Ps. 70:9: "When my strength shall fail, do not Thou forsake me." Hence a man may merit to be restored after a fall. Objection 2: Further, a man's works benefit himself more than another. Now a man may, to some extent, …

Letter xvi to Rainald, Abbot of Foigny
To Rainald, Abbot of Foigny Bernard declares to him how little he loves praise; that the yoke of Christ is light; that he declines the name of father, and is content with that of brother. 1. In the first place, do not wonder if titles of honour affright me, when I feel myself so unworthy of the honours themselves; and if it is fitting that you should give them to me, it is not expedient for me to accept them. For if you think that you ought to observe that saying, In honour preferring one another …

Psalms
The piety of the Old Testament Church is reflected with more clearness and variety in the Psalter than in any other book of the Old Testament. It constitutes the response of the Church to the divine demands of prophecy, and, in a less degree, of law; or, rather, it expresses those emotions and aspirations of the universal heart which lie deeper than any formal demand. It is the speech of the soul face to face with God. Its words are as simple and unaffected as human words can be, for it is the genius …
