The form of worship practiced in the Free Presbyterian Church of Scotland is governed by the Regulative Principle*.

* The Regulative Principle, as it applies to public worship, states that only those elements (of worship) that are instituted or appointed by command or example, or which can be deduced by good and necessary consequence from Scripture, are permissible in worship; and that whatever is not commanded or cannot be deduced by good and necessary consequence from Scripture is prohibited.
