The "JW's" are Arian heretics. A simple refutation of Arianism used by St. Augustine, St. Athanasius etc that the heretics could never answer was that the Son of God told us to be baptized in the "Name of the Father and of the Son and of the Holy Ghost" (Mat 28:19). Now, since He says Name, He teaches that the Three are One. This is the Name of the Trinity, the one Name of the Triune God. Arianism is a detestable heresy, condemned by all of Sacred Scripture. Were it not for the Protestant revolution and the disastrous principle of private interpretation it introduced, Arianism would never have reappeared. St. Peter, St. Paul, St. John, St. Thomas etc all teach Jesus is God and Creator, (2 Pet 1:1; Acts 20:28) Phil 2:6; Rom 9:5; Col 1:16-17; Jn 1:1;3; Jn 20:28), it was not a mere man, but God who redeemed us in His own blood, as these verses teach, and whoever does not know and believe that, and moreover is not baptized properly is not by any means a Christian, is a heretic, is yet in his sins, and is on the way to hell.

JW's assert an absurdity when they say that Jesus didn't create, contrary to these passages, or when they say He was supposedly a creature but was still instrumental in the creation of others. That is impossible and senseless, because no creature can create anything, nor be an intermediary in the act of creation, which only the Creator can accomplish and requires infinite power, since God brings a being into existence from non-being without a material cause. And Genesis clearly shows us God alone creates all things by His Word and His Spirit, just as St. John says. God's Word is in Him, and is inseparable from Him, just as is His Spirit. When God decides to create, He creates through His own intellect and will alone, His Word and His Spirit. When God says "Let Us make man", there is the plurality of the Godhead revealed right there in Gen 1:26. God conceives the object He wishes to create, and merely wills it into existence, He speaks the Word and they are called into being, He breathes His Spirit and they have life, as Psa 33:6 says.

The Name YHWH, as other posters have mentioned, describes God's eternal and self-subsistent nature. Jesus uses the same Name to describe Himself (Jn 8:24;8:58) and also declares faith in His divinity to be absolutely necessary for salvation. We know this by divine revelation, and we are bound to believe it to be saved. But although it is above reason, since no one can comprehend the Godhead, it is not opposed to reason, the Church who is infallibly guided by the Holy Spirit, and those whom She has approved can help us gain some understanding, as Vatican I declares, "Now reason, does indeed when it seeks persistently, piously and soberly, achieve by God's gift some understanding, and that most profitable, of the mysteries, whether by analogy from what it knows naturally, or from the connection of these mysteries with one another and with the final end of humanity; but reason is never rendered capable of penetrating these mysteries in the way in which it penetrates those truths which form its proper object." We believe in divine revelation because we are taught by the authority of Christ and His only true Church, not on what we judge or prefer to be true.

God is a Trinity, because He is eternal and self-subsistent. In a Being who is self-subsistent, St. Thomas proves at length, there can be no potentiality, nothing that God can become that He is already not. But if His intellect were not His Essence, His Intellect would be related to Him as act to potency. Therefore, His Intellect or His Word is His own Essence. And likewise, His Will or His Spirit is also His own Essence. God, His Word and His Spirit are One Being. The Word begotten of the Father alone, the Spirit proceeding from the Father and Son. A distinction of Person within the unity of Essence. The Holy Trinity. An analogy used by some of the Fathers was the light and heat proceeding from the sun, but in a way one with and inseparable from it.

Thank you for this.  I printed it out so I can read it and look of the verses at leisure.  I did look up 2 of them

2 Pet1:1  their bible the NWT has that verse translated...of our God and THE savior Jesus Christ.
So they add "the" implying that Jesus isn't God.

Acts 20:28 The NWT has...the blood of His own son .  Again, Jesus is not God.

Their bible is a fiction but the only one that has any meaning for them.

It is a shame she is a wonderful person and a former Catholic who prayed the rosary every night with her family when she was a child.  I wonder what happened to her for the drastic change from the truth to a gigantic lie that she believes now.

Jehovah's Witnesses go so far as to teach that Jesus is actually St. Michael the Archangel himself! They maintain that Our Lord was Michael the archangel prior to his coming to earth. They assert: "Scriptural evidence indicates that the name Michael applied to God's Son before he left heaven to become Jesus Christ and also after his return" (Aid to Bible Understanding, Watchtower Bible & Tract Society, 1971, 1152).

God bless you for trying to bring your friend back to the faith.
However, I still hold that you are allowing her to dictate the debate by arguing her points from her heretical reference book (I refuse to call it a bible).
I would prove to her the error of this reference, upon which she is risking her salvation.

The New World Translation of the Christian Greek Scripture is a fumbling translation of the New Testament that no reputable Greek scholar will endorse. The Translation has been altered to fit the heresy. For instance, the Greek word for "other," allos, does not appear in the Greek text of Colossians 1:16, 17 but it is inserted four times in their translation to make Christ appear as part of the creation, and therefore fit their doctrine that He is a created son, another god. "...because by means of Him all other things were created." This and dozens of other passages make the New World Translation a travesty of God's Word.

Does your friend know the truth about the founder of this diabolical cult?

In 1847, a Brooklyn haberdasher, Charles Taze Russel, announced that he possessed all the truth. In his many volumes, Russel "left scarcely one great truth or fundamental doctrine untouched with his unholy and unwarranted conclusions," (Dr. William E. Biederwolf). As a careful study will reveal, Russel's writings serve as a broad base upon which the Jehovah's Witness structure is built. Presently the Jehovah's Witnesses are following the fallen conclusions of a rascal who was divorced by his wife, was in trouble with the courts, and who fleeced his followers with "miracle wheat" sold at an exorbitant price, which he claimed would produce 15 times as much wheat as an ordinary bushel.

She knows some of it but the Watchtower has a way of hiding every thing and they change their doctrine about every 10 years. If she would read the site you linked she wouldn't believe it.  If she gave it any credence at all I think she would say that mistakes were made in the past and corrected.  She would praise them for admitting the errors and correcting them.

She is in for the long haul unless the Holy Spirit enlightens her.

I would hope that I can and have planted some seeds of truth.

They also don't celebrate holidays and birthdays at all, Easter and Our Lord's Nativity included, on the basis that they're "pagan" or something. How can one claim the moniker of "Christian" but dismiss those days? I don't get it.

Oh yes! The same as the Mormons. Freemasons are behind many heretic sects.
