Similarily, Paul told the Corinthians :
" When I come to you,
it was not with any show of oratory or philosophy,
but simply to tell you what God had guaranteed ".
{ 1 Corinthians 2:1 , The Jerusalem Bible }

Like Jesus, his reasoning was based solidly on the Scriptures..
{ Acts: 17:2 }

The Bible encourages the use of one's mental faculities to the full but not without restraint.
However, the burden of responsibility for keeping our thinking in harmony with that of Jehovah is based on the individual Christian, not the congregation.

Thus , when a number of Ephesians publicly renounced their practice of spiritism and became Christians,

Paul did not take it upon himself to burn their books,
but a " number of them who had practised magic collected their books and made a bonfire of them in public. "
{ Acts 19:19, JB}

Why did theses Christians feel it necessary to burn their own books ?
