Dr. Watts’s ‘grand design’ in his version of the Psalter was ‘to teach’ the ‘author to speak like a Christian.’ Charles Wesley took St. Augustine’s view, that we ought to hear the voice of Christ in all the psalms. His version of Ps. xlv. is typical of his attitude toward the Psalter as a whole.

My heart is full of Christ, and longs

Its glorious matter to declare!

Of Him I make my loftier songs,

I cannot from His praise forbear;

My ready tongue makes haste to sing

The beauties of my heavenly King.

In 1762 Charles Wesley took advantage of a time of physical weakness to write a large number of verses, forming a kind of running commentary on the Holy Scriptures. They are, for the most part, purely devotional; but the events of the time and, perhaps, of the day on which a poem was written are mirrored in some of the verses. In the preface he says—

Many of the thoughts are borrowed from Mr. Henry’s Commentary, Dr. Gell on the Pentateuch, and Bengelius on the New Testament. Several of the hymns are intended to prove, and several to guard, the doctrine of Christian Perfection. I durst not publish one without the other. In the latter sort I use some severity.

On this point the brothers differed, and especially as to the method of treating those who discredited the doctrine by extravagance in teaching or by inconsistency of life.
