When I look at the 40+ translations on Biblegateway for Matthew 6:7 -- praying like Pagans, it would seem many prefer 'babbling' or 'repeating' or both. I thought the verse meant that the Pagans were trying to control the god by reciting various formulas or incantations (I don't recall where I learned that). So Jesus meant that controlling the god is not the purpose of prayer. The next verse is 'Your Abba knows what you need even before you ask,' so no need to ask. Then the text has the Our Father which is not necessarily a prayer of petition. How could it be if Jesus has just said no need to ask. Rather think of exclamations.  "!!! You give us each day our daily bread !!!" Not a petition. Not trying to control the god. For the historical Jesus, the Mass would resemble Pagan babble 

As for Fatima, it came out of the minds of those children.  But what about the phenomenon where thousands there at Fatima supposedly saw the sun whirling in the sky. What about their minds? Fascinating
