Thank you for the question on the Bible being media.
When I think of “media”, I usually think of someone or something being communicated to another person.
One can view the Bible as the content of the media. The means of communication can be reading, drama or stories of the Bible, debate about the Bible, sermons, songs, etc. though a person or some visual aids.
In a Christian context, someone, usually a leader is communicating his/her observations, interpretation of the text with it’s application to the listener.
SUMMARY: The content of the Bible may become the means of the media through some instrument.
