And when the Magisterium gives approval for a Catholic Biblical Scholar to publish with an 'imprimatur', it means the Magisterium is approving of what is written and finds nothing objectionable.

'Magisterium' simply means 'teaching authority'. Approved Catholic Theologians and Biblical scholars are a part of the way the 'magisterium' functions. The 'magisterium' is more than 'the bishops'; and even some bishops , if not all, are also Biblical scholars.

I presume you must know that.
