Which set of doctrines is accepted and believed by the vast majority of Christians? To get started, I think the doctrine "God exists" must surely be the least controversial of all.
Note: This is essentially the polar opposite to my recently asked (and closed) question What are the most controversial and heatedly debated doctrines in Christianity?
EDIT: a probably more on-topic polar opposite question: What is an overview of denominational doctrines that are most commonly defended by apologists against objections from other denominations?
Stack Exchange has a long storied history with anathematizing "List questions"
- I think the maxim 'citation needed' applies here.
