mathew 5:19 and revelation 22:18-19 come to mind
mathew 5:19
19 whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: But whosoever shall do and teach
them, the same shall be called great in the kingdom of heaven.
Revelation 22:18-19
18 for i testify unto every man that heareth the words of the prophecy of this book, if any man shall add unto these things, god shall add unto him the plagues that are written in this book:
19 and if any man shall take away from the words of the book of this prophecy, god shall take away his part out of the book of life, and out of the holy city, and
from the things which are written in this book.
I dont think church doctrine would override these
edit to add.
It was the church doctrines that had become impossible to stand on that had jesus at odds with the priests. They were making it impossible with their manmade interpretations and jesus showed them their error on every occasion they met. This was what caused them to hate him because he stood on the pure word of god while they had it fenced arround with their laws.
