:So the first paragraph would read: "The churches of Christ are non-denominational, autonomous Christian congregations. Members consider themselves "Christians only," and do not identify as Catholic, Orthodox or Protestant. These churches comprise about 2,000,000 members in over 40,000 individual congregations worldwide." 
 :I made a slight change in your wording to reflect the view of the members of themselves rather than stating it as a fact which might not hold up.
