It’s about finding the right hills to die on:

• First-rank doctrines are those that are essential to the gospel itself.
• Second-rank doctrines are urgent for the health and practice of the church to such a degree that they tend to be the cause of separation at the level of local church, denomination, and/or ministry.
• Third-rank doctrines are important to Christian theology, but not important enough to be the basis for separation.
• Fourth-rank doctrines are unimportant to our gospel witness and ministry collaboration.
