In our service book, the list of heterodox ideas explicitly renounced is pretty limited. We don't have any of the following, for example:
- The only morality is sexual morality, and you just need to make sure no one finds out
- Hypocrisy is a-ok
- When you're received into a new church, you become too cool for school
- Bickering over Scripture is a great idea
- Murder is OK if it helps you and the victims seem kind of abstract
So some people, me included, are received without having to think about this stuff too much.
