Wow, this is simply a classic example of how two different sets of people can look at the same chunks o' Scripture and see opposing theories proved -- and that is why I try to avoid "proving" stuff From Scripture.
What I have found on authentic Catholic websites and sources, such as NewAdvent.org confirms my assessments of the situation.
Remember, I am not anti-Catholic, I am pro-God.
The only time I raise an issue with my brothers and sisters of the Catholic faith is when I see something presented which might be misunderstood and result in someone appreciating God's glory less than he should.
That was the reason behind the research project and subsequent sidebar on "who is The Rock?"
Issues like that are rarely misunderstood at the highest levels of the Catholic church - but can be misunderstood by the laity or by the observers of the Catholic faith. For instance, betty boop posted this direct quote from Pope Benedict XVI in reference to the name of God, The Rock. (That Name was announced in the Song of Moses, Deut 32:1-4)
And she cried out with a loud voice and said: Blessed art thou among women and blessed is the fruit of thy womb.
Et exclamavit voce magna et dixit benedicta tu inter mulieres et benedictus fructus ventris tui (NewAdvent)
And she spake out with a loud voice, and said, Blessed (eulogeo) art thou among women, and blessed (eulogeo) is the fruit of thy womb. (KJV with Greek)
I could find no confusion between living water and holy water on the Catholic Encyclopedia at NewAdvent.
And finally, on the difference between baptism by another mortal in water - either to Moses, to repentance (John's baptism), to Jesus or collectively, to the Father, Son and Holy Spirit - as compared to baptism by the Holy Spirit - there has been no dispute in either of the two linked articles.
The living water is the Holy Spirit. Holy water is water which has been blessed. And whereas mortals may baptize us to Him, Jesus Christ Himself is the one who baptizes us with the Holy Spirit.
My point is simply, to God be the glory!
"-- and that is why I try to avoid "proving" stuff From Scripture."
Yeah, me too, like salvation, heaven, hell and that "God" stuff. It is so confining and does nothing for my self esteem.
