Whenever a man takes upon him to make additions to the Scriptures, he is likely to end with valuing his own additions above Scripture itself.

Whenever a man takes upon him to make additions to the Scriptures, he is likely to end with valuing his own additions above Scripture itself.

We see this point brought out most strikingly in our Lords answer to the charge of the Pharisee against His disciples. He says, "Why you disobey the commandment of God because of your tradition?" He strikes boldy at the whole system of adding anything,as needful to salvation,to God's perfect word.He exposes the mischievous tendency of the system by an example.He shows how the vaunted traditions of the Pharisees were actually destroying the authority of the fifth commandment.
