Penitential Psalms

The Penitential Psalms or Psalms of Confession, so named in Cassiodorus's commentary of the 6th century AD, are the Psalms 6, 32, 38, 51, 102, 130, and 143 (6, 31, 37, 50, 101, 129, and 142 in the Septuagint numbering).
These psalms are expressive of sorrow for sin. Four were known as 'penitential psalms' by St. Augustine of Hippo in the early 5th century. The fifty-first Psalm (Miserere) was recited at the close of daily morning service in the primitive Church. Translations of the penitential psalms were undertaken by some of the greatest poets in Renaissance England, including Sir Thomas Wyatt, Henry Howard, Earl of Surrey, and Sir Philip Sidney. Before the suppression of the minor orders and tonsure in 1972 by Paul VI, the seven penitential psalms were assigned to new clerics after having been tonsured.
