Simplify the following text for a Grade 6 native English-speaking person.
Original: Even though most Protestants look at scripture alone and no other authority , some theologians say that the Bible itself teaches against sola scriptura . They believe that if a person believes in the whole Bible then that person can not not believe in sola scriptura .
Simplified: Sola scriptura ( Latin for `` by scripture alone '' ) means `` The Bible only '' .
