Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me. (John 5:39)
We search the Scriptures to have eternal life.
It is the Scriptures that speak and testify of Jesus.
Not: Search the Scriptures and the Sacred traditions...that accompany the Scriptures and add to the words of God.
In Sacred traditions people only think they have eternal life, which is why Jesus told them to leave their own traditions and go to the Scriptures, that they may have eternal life.
And ye will not come to me, that ye might have life.
If we don't search the Scriptures, we do not come to Jesus,. They that search their Sacred traditions do not come to Jesus Christ, but to another christ.
Doesn't say Scripture alone.
