I don’t even think we need to actually go into the Greek to understand what a falsehood that statement is. Jesus was talking to Nicodemus undoubtedly in a language that Nicodemus understood. Nicodemus’ understanding is perfectly clear from his question to Jesus.
John 3: 4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
Now, Nicodemus’ mother’s womb wasn’t “from above” and if he understood that it would be “the second time” ie again we can be assured he understood the statement from Jesus to mean “born again”.
Catholics may not realize that they actually should be totally embarrassed with statements like the one you just made but it’s pretty obvious to Bible believers that they should.
And if you were misinformed about something this simple what else have you been lied to about?
Get back to me after you actually read and understood it.
