Can any christian read Koine Greek?

"Lean not to a man's languages" (Proverbs 3:5; Isaiah 55:8-9)! 

"GOD reveals by His Spirit" (I Corinthians 2:10)!

Now you're trying to take GOD's job away from Him of "revealing by His Spirit" like you have "baptism" (John 1:33) and "communion" (II Corinthians 13:14).

"...GOD is a jealous GOD, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that HATE ME" (Exodus 20:5) and you "HATE HIM" when you take away His jobs believing, HE NEEDS YOUR HELP (Job 38)!

Yikes man, pretty much all of us can. Even before the Internet we had Strong's Concordance and now the entire Greek New Testament is a click away. Blueletterbible.org is the best developed and has been around the longest but there are scores of them now. 

Your quotation is the first line from the Jewish 'Shema' 

I think Chi Girl does

There was a poster on this site who claimed to have read the New Testament in its original language...But she couldn't name the language...

I was unaware that it still existed.... The Orthodox Greek Catholics still use it ... 

WOW! Google translated your piece...

No. Only the ones who learn it.

Google translate can: "Hear, O Israel, our Lord our God"

not me.........
