The Scope and Sweep of the Psalms

Athanasius on the comprehensiveness and sufficiency of the Psalms:

Let whoever reads this Book of Psalms take the things in it quite simply as God-inspired; and let each select from it, as from the fruits of a garden, those things of which he sees himself in need. For I think that in the words of this book all human life is covered, with all its states and thoughts, and that nothing further can be found in man. For no matter what you seek, whether it be repentance and confession, or help in trouble and temptation or under persecution, whether you have been set free from plots and snares or, on the contrary, are sad for any reason, or whether, seeing yourself progressing and your enemy cast down, you want to praise and thank and bless the Lord, each of these things the Divine Psalms show you how to do, and in every case the words you want are written down for you, and you can say them as your own.

The Psalter's Very Special Grace

From the Letter of St. Athanasius to Marcellinus on the Interpretation of the Psalms:

Among all the books [of the Bible], the Psalter has certainly a very special grace, a choiceness of quality well worthy to be pondered; for, besides the characteristics which it shares with others, it has this peculiar marvel of its own, that within it are represented and portrayed in all their great variety the movements of the human soul. It is like a picture, in which you see yourself portrayed and, seeing, may understand and consequently form yourself upon the pattern given. Elsewhere in the Bible you read only that the Law commands this or that to be done, you listen to the Prophets to learn about the Saviour's coming or you turn to the historical books to learn the doings of the kings and holy men; but in the Psalter, besides all these things, you learn about yourself. You find depicted in it all the movements of your soul, all its changes, its ups and downs, its failures and recoveries.
