11. The Puritans did not all believe in Exclusive Psalmody
The impression is often given by those who promote exclusive psalmody that every Reformed stalwart of the past was an exclusive psalmist. This could not be further from the truth. Many of the great and good men of the past who were reformed in doctrine did not hold to the exclusive singing of the Psalter.
Some prominent examples:
1. Matthew Henry. In his commentary on Ephesians 5:19 the renowned and much loved expositor had this to:
By psalms may be meant David's psalms, or such composures as were fitly sung with musical instruments. By hymns may be meant such others as were confined to matter of praise, as those of Zacharias, Simeon, &c.
On Colossians 3:16 his commentary reads:
Singing of psalms is a gospel ordinance - the Psalms of David, and spiritual hymns and odes, collected out of the scripture, and suited to special occasions, instead of their lewd and profane songs in their idolatrous worship.
