THE rule of this knowledge, faith, and obedience, concerning the worship of God, in which is contained the whole duty of man, is (not men's laws, or unwritten traditions, but) only the word of God contained [viz., written] in the holy Scriptures; in which is plainly recorded whatsoever is needful for us to know, believe, and practice; which are the only rule of holiness and obedience for all saints, at all times, in all places to be observed.
