: You haven't proven descent.  You have certainly proven they took 15 churches in tact and the article now reflects this. The problem is you need to show some relationship between Maranatha and the other several hundred churches or show how the Maranatha churches birthed the other churches.  Descent is not easy to prove.  Something like "the US wing/division... is mainly made up of former Maranatha churches" may be justified but what about the rest?
