Talmudic Judaism (the predominate form of modern Judaism) is an antiChrist religion. Are you looking for specific quotes from the Talmud? I provided examples already, such as that they believe that Jesus was stoned to death, wasn't resurrected, is not God, was a false prophet, possessed by demons, and is currently being tormented in Shoal in boiling excrement. The Talmud also teaches that God does not know the hearts of believers and can be mistaken in his understanding. The god of the Talmud and God of the Bible are fundamentally different characters. All of this together should be a red flag for any Christian.
"Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son." - 1 John 2:22 KJV
"Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God: And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world. Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world." - 1 John 4:2-4 KJV
AntiChrists are our enemy for the sake of the Gospel, but we are still to have God's love for our enemy. Even Saul would have denied Christ before he became Paul. Calling something antiChrist is not necessarily to say that someone is destined for damnation (as only God can know that) but it is to say that that person is in a bad place in life and on a road to bad things.
By Biblical definition, per 1 John 2:22 and 1 John 4:3, Talmudic Jews are antiChrist and liars in that respect. By those passages, they are not of God. At least, not in their outward spirit. An antiChrist is basically something or someone that desperately and especially needs God's help and intercession for salvation.
Saul/Paul is an interesting point in all of this. Because through his revelation, and through his repentance, Christ set him on the right path. Saul was a liar, antiChrist, and not of God. Paul was of Christ and God. And it was only through his perspective of being an antiChrist that he became such a useful teacher for everyone. God works in mysterious ways, and it does seem that Saul's journey as an antiChrist served God's purposes. The same could be true of any number of people in any number of circumstances. Maybe a murderer finds Christ and becomes a new person, maybe an adulterer, a drunkard, or a thief finds Christ and through their wretched lives they lived before have a deepened understanding of how much they have failed without God the Son, God the Father, and the Holy Spirit.
When we get passed the sticker shock of "How dare you question the worldly power of modern Judaism!" We see that there an interesting question underneath that can be explored from a Christian perspective untainted by antiChrist perspectives. But believing that anyone that denies Christ can still be of God is a contradiction of 1st John.
If you know anyone that recites the standing prayer but denies Christ, then you do therefore know an antiChrist that repeats the standing prayer.
