Okay....that's good. I don't either so let's just read the salient points in the Greek and see what they say!
[Matthew 6:5] But when you pray (4336 proseuchomai (pros-yoo'-khom-ahee) to pray to God, i.e. supplicate, worship) do not be like the hypocrites (5273. hupokrites (hoop-ok-ree-tace') an actor under an assumed character (stage-player), i.e. (figuratively) a dissembler ("hypocrite") for they love to pray standing in front of the synagogues and on the street corners to be seen by men.
The above verse very plainly tells us prayer should be a private thing....not a public display.
[Matthew 6:6] When you pray, go into your room, close the door and pray to your Father (3962. pater (pat-ayr')apparently a primary word; a "father" (literally or figuratively, near or more remote) who is unseen. Then your Father, who sees what is done in secret, will reward you.
Again, we see that private prayer to Our Father is reinforced instead of any kind of public display.
[Matthew 6:7] And when you pray, do not keep on babbling (945. battologeo (bat-tol-og-eh'-o) to stutter, i.e. (by implication) to prate tediously; use vain repetitions) like pagans (1482. ethnikos (eth-nee-kos') national ("ethnic"), i.e. (specially) a Gentile; heathen (man), for they think they will be heard because of their many words.
Well.....I don't believe there is too much we can say about verse 7 except.....God doesn't pay much attention to folks who just "prate tediously"....especially when they're not talking to Him!
Now I realize that you are going to say....That's just your interpretation". You're right! God gave me a brain and the ability to think things out.
Here is some various translations of [Matthew 6:7]. I'm certain you will agree that all say the same thing.
Here is the Douay....pretty much the same as the others.
[John 5:39] Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
Our Lord commands us to search Him out through the Holy Scriptures. We don't need a Magesterium to see what he is saying!
So why are there several different thousand Protestant denominations.?
