Augustine of Hippo
Patristic
A.D. 354–430
“"Begin to the Lord in confession" [Psalm 147:7]. Begin with this, if you would arrive at a clear understanding of the truth. If you will be brought from the road of faith to the profession of the reality, "begin in confession." First accuse yourself: accuse yourself, praise God. What after confession? Let good works follow. "Sing unto our God upon the harp." What is, "Upon the harp"? As I have already explained, just like the Psalm upon the psaltery, so also is the "harp:" not with voice only, but with works.”
