There's a fancy Latin term that can help you understand a key part of the Catholic faith: It's called Sola Scriptura.  And the Church rejects its fundamentalist, rigorist approach.  You don't reject it apparently, wanting to see everything (preferably within quotes from Jesus...except when He tells us that we should come to Him as a child....or within one of the Gospels...preferably one of the synoptic gospels.....preferably within the new testament...") in Scripture.   Well and not everything in Scripture do you really want to be reminded of.   And you gravitate to revisionism on these points too..."that was the context and culture of the day..so all that should be set aside..it doesn't apply in any sense to us today....marriage one flesh?  Well that was aspirational, contextual, dontic, etc. etc.
