These Dissenting Brethren of Westminster articulated the denominational theory of the church in several fundamental truths:
First, since a person is unable to always see all of the truth clearly, differences of opinion about the outward form of the church are inevitable.
Second, even though these differences do not involve fundamentals of the faith, they are not matters of indifference. Every Christian is obligated to practice what he believes the Bible teaches.
Third, since no church has a final and full grasp of divine truth, the true church of Christ can never be fully represented by any single ecclesiastical structure.
Finally, the mere fact of separation does not of itself constitute schism. It is possible to be divided at many points and still be united in Christ.
