Did Paul’s authority come from Jesus?
As far as I can tell, yes.
Jesus’s own brother described himself as a bond-servant to Christ. Do you know ANYONE who would sign up to be a bond-servant to their own brother?
Paul tells slaves to submit to their owners, even those who treat them harshly. If I was ever gonna change the bible, that woulda been one of the verses I dropped. The fact that there are seemingly embarrassing verses [like Jesus’s own family questioning His sanity] is a sign that they did NOT change the bible.
