Sectarianism is limitation. Some truth taught in Scripture, some part of the divine revelation, is apprehended, and the heart responds to it and accepts it. As it is dwelt upon, expounded, defended; its power and beauty increasingly influence those affected by it. Another side of truth, another view of revelation, also contained in Scripture, seems to weaken, even to contradict, the truth that has been found to be so effectual. and in jealous fear for the doctrine accepted and taught, the balancing truth is minimized, explained away, and even denied. So on a portion of revelation, on a part of the Word, a sect is founded, good and useful because it preaches and practices Divine truth, but limited and unbalanced because it does not see all truth, nor frankly accept the whole of Scripture. Its members are not only deprived of the full use of all Scripture, but are cut off from the fellowship of many saints, who are less limited than they, or limited in another direction.
