Doctrine is a set of beliefs.
Christian doctrine would be those beliefs that are consistent with the teaching of Jesus and his disciples.
Incorrect doctrine (which could be a matter of interpretation) is called heresy; it is a false teaching.
A lifelong student of the Bible, Peter DeHaan, PhD, wrote the 700-page website ABibleADay.com to encourage people to explore the Bible. His main blog and numerous books urge Christians to push past the status quo and reconsider how they practice their faith in every area of their lives.
