The non EPer's #1 Objection was a total let down (respectfully).
He also stated (paraphrased): "I would not object to singing
only the Psalms."
But, wouldn't that go against his claim to hold to the RPW? Because, if he believes that the singing of uninspired Psalms is
authorized, then it follows he believes it's
commanded; thus, he should be adamantly against the
exclusive singing of the Psalms, since it doesn't (according to his understanding of the RPW) include that which he apparently believes is commanded (uninspired hymns).
