I found this section helpful from Mark Dever and Michael Lawrence out of the book Perspectives on Worship: 5 Views. This is just a snippet of their response to Timothy Quill’s argument for Liturgical worship (Lutheran Style). I don’t see anything inherently wrong with liturgical worship, maybe even we (as Baptists) could use it more, however what Dever and Lawrence say still rings true.
At the end of the day, the justification for liturgical worship seems to be limited to the historical and the pragmatic: Christians have found this helpful for centuries, and it is still helpful; so we should not abandon it for contemporary forms. Early on, Quill acknowledges that Scripture does not explicitly prescribe the use of ceremonies beyond baptism and the Lord’s Supper. And while much is made of the scriptural character of liturgical rituals, the fact remains that the only inspired ordering of those words is the Scriptures themselves. So, as he states at the beginning, from within the liturgical perspective, liturgy itself is an adiaphoria (= neither morally mandated nor forbidden)
