Deuteronomy 12:16

Verse 16. Only you shall not confound these things with the truths derived from the Divine Humanity of the Lord, which you shall receive into the soul as coming direct by influx from heaven. [Note (verses 13-16).—A distinction seems to be made here between the essentials and those things which are not essential in worship. All that proceeds from the one only God as revealed in the person and character of the Lord Jesus Christ is to be sacred and inviolate, and all other things are to be considered as comparatively unessential.]
