Here are some references for further reading on the so-called Regulative Principle of Worship, along with some classic treatments of the sufficiency of Scripture.
One might also consult the systematic theologies produced after the
Puritan era, including the recent one by Robert Reymond. See also
commentaries on the Westminster Confession and Catechisms.
