This is spin; if Jesus wanted to say "physical birth" He would refer to "womb", just like Nicodemus does in his question. He would not respond with a riddle forcing Nicodemus to figure out that womb=water. The entire reference to borth of the water and spirit is a plain reference to baptism which combines these two elements precisely.
I see how you interpret the Bible - by imagining what words the Lord should have used. The context is quite clear. The fact the water baptism is not mentioned here and is not required for salvation make your position indefensible.
But I forget ye be RCC and that religion’s dogma requires you to ignore clear Biblical meaning.
Sorry about that.
**The entire reference to borth of the water and spirit is a plain reference to baptism which combines these two elements precisely.**
Our priest has been saying all week that John does not put anything into his Gospel without a definite meaning. I think you have the meaning here.
Blessings for the 50 days of Easter!
