I want to know the answer to the following question:
What belief is the emphasis of the Plymouth Brethren?
All the background I'm provided with is that "Although the group refused for many years to take any denominational name to itself—a stance that some of them still maintain—the title The Brethren, is one that many of their number are comfortable with in that the Bible designates all believers as brethren.". Is that enough to answer the question?
Answer: no
