theologically shallow, biblically uninformed?

Good quote using two phrases I think are useful to help other brothers and sisters evaluate their corporate worship song texts:

"Dr. Boice had often expressed concern about contemporary Christian worship. His concern was not limited to the style of the music, but focused more specifically on the content of its lyrics, which he considered theologically shallow and biblically uninformed." GPTG p. 11

Remember, without the standard [God's Special Revelation, the Bible] the risk becomes being enslaved by whatever "privatized spiritual experience" a group of people may want to call worship, and quite possibly risking idolatrous flirtation if the standard is assented to but muted, or rank idolatry if the standard is absent, because something infinitely inferior to God has replaced the standard for our worship. Two kinds idolatry -- worshipping a false god or worshipping the true God falsely [OT syncretism].

And theologically true but shallow statements sung incessantly without Biblical definition can lead to defining those broadly true but shallow statements in whatever way one wishes to define them [what the Bible means to me] because nature abhors a vacum. The self is the natural default when the standard is muted, missing, or redefined.
