Doctrines (6)
(Other definitions for tenets that I've seen before include "Doctrines of belief" , "Doctrines held to be true" , "Principles of belief" , "Convictions" , "We stand by these" .)
'doctrines' is the definition.
(dogma is a kind of doctrine)
This is all the clue.
(Other definitions for dogmas that I've seen before include "Doctrines to be accepted without question" , "Set of principles set down as incontrovertibly true" , "Doctrines put forward by church" .)
