The concluding command: 'What thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it.' This establishes sola Scriptura (Scripture alone) principle. The Hebrew shamar (שָׁמַר, guard/observe) demands protection of God's revealed word. Two temptations are prohibited: adding to (yasaph, יָסַף) and subtracting from (gara, גָרַע) Scripture. Human tradition must not supplement divine revelation; liberal reductionism must not edit uncomfortable commands. God's word is complete, sufficient, and authoritative. This command is repeated in Deuteronomy 4:2 and echoed in Revelation 22:18-19, framing all Scripture with this warning.
Historical Context
Later Judaism's oral law tradition arguably violated the 'add not' command—rabbinic fences around Torah added requirements God didn't mandate. Jesus criticized traditions that 'made void' God's commandments (Matthew 15:3-6; Mark 7:8-13). Conversely, liberal theology's editing Scripture to remove 'offensive' parts violates 'diminish not.' The Reformation's sola Scriptura recovered this principle, rejecting both traditionalism and rationalism in favor of Scripture's final authority. Every generation faces pressure to add human wisdom or subtract difficult teachings.
Questions for Reflection
How do church traditions risk 'adding to' God's word when elevated to equal authority with Scripture?
In what ways does modern theology 'diminish' Scripture by rejecting difficult doctrines or moral commands?
How do we maintain Scripture's authority while applying it to situations not directly addressed in biblical times?
