Colin Dunlop, former Dean of Lincoln, articulates the nature of corporate identity and confession in Anglican worship with these words:
We make our confession as members of the Church, "members one of another." We confess not only our own private sins, but . . . our share in that whole aggregate of sin which all but crushed our Master in the Garden of Gethsemane.
The psalms are the praise of Christ in His Church, or of the Church in Christ. They are not an individual's prayer, but the prayer of the whole Body; they are the very stuff of what we prosaically call "corporate worship."
