Our View of Other Christians and Christian Doctrines

Do we think we are the ones with the “correct” doctrine and practice?

We don’t see ourselves that way — nor do we see any other Christian group that way. The Church is a gathering of imperfect people, and new challenges constantly arise that require discernment under the guidance of the Holy Spirit — who alone is perfect among us.

That’s why we hold to the ancient principle:
Ecclesia semper reformanda est. (The Church is always reforming.)

When it comes to doctrine, we hold to a saying from the 17th century:
In necessariis unitas, in dubiis libertas, in omnibus caritas.
(In essentials, unity; in non-essentials, liberty; in all things, love.)

Put more simply:

In essential or foundational matters (those related to salvation) — unity
(1 Corinthians 12:12–13; John 17:20–23)
In what is not essential or not clearly revealed — freedom
(Romans 14)
In all things — Christian love
(1 Corinthians 13)

We see ourselves as members of the Universal Church of Christ (katholikos in Greek) — together with all other true disciples of Jesus, regardless of which Christian community or denomination they currently belong to.
