First of all, Doctrine is far more than "theory". Theory is putting it VERY lightly.
Secondly, yes, these doctrines are updated constantly with the new rise of many technologies and whatnot.
Infact, everyone knows about Vatican II in the 60's when MAJOR reformation within the Church occurred... :angry: but thats a topic for another time.
Like I said in another post, there are bad people in every organization, evil people who will hide behind the goodness that the organization wants to and, REGARDLESS of these evil doers, CONTINUES to portray and promote.
So yes, they really DO have the right to continue telling us what is right and wrong.
Its worked for 2000 years.
Also, in reference to the ethics practices that are not those directly attributed to Christ...heh...I'd like to know what you think those are...and I will be happy to show you where those "ethics" or practices or traditions or whatever you'd like to call them, come from and ARE clearly attributed to Christ. Peace!
