That's some 4k listener podcast, of Lutherans who were excommunicated by their own Church and for all I know, Lutherans and Protestants broadly, really only on scripture, on scripture that has been edited by Churches and events they don't recognize as truly Christian. 

To give an example of how much they rely on scripture, they will tell me Mary had 6 other kids after Jesus and she didn't die a virgin, when the protoevangelion of James clearly recounts the story of Mary, where she was raised in a temple and as she approached puberty, because the menstrual cycles would be considered unclean, they decided for a widower to take care of her, the pull lots, where Joseph is to be her care taker, as a man who already had sons from his previous wife. 

And all this, I remember from my own education and just from looking at the story online. And yet I am to listen to these people tell me, ''Mary had kids after Jesus.'' And they will deny that story because, ''It's not in The Bible.'' 
Ahh yes, the pre-selected texts from Churches that are not seen as, ''actually Christian.''
