I know I'm going to regret this, but since you seem to be a tolerant person of good will, I will respond honestly and respectfully. Hopefully neither of us are like the people who want to execute that poor journalist this article was about, and can tolerate each other's human rights to think what we wish to think.
John 14:11 is perhaps the second-most obvious (though there are countless other examples): "Believe me when I say that I am in the Father and the Father is in me; or at least believe on the evidence of the miracles themselves."
Absent the claim about believing through miracles, a claim of a prophet that is explicitly rejected in the Torah as a method of proof. The test is if he asks us to change our religion, in which case he is a false prophet, not if he produces miracles - which the Torah tells us to not heed.
The rest of that sentence, by the way, about G-d being in one etc, could nearly be said by any Chabad Chasid, though not in precisely those words.
In this text, he's using "in" in an existential manner; it refers to coexistence and coequality of essence and substance.
You're adding in the trintarian stuff now, do you really want to try to prove the Council of Nicene from the NT?!
The most-most obvious, however, is John 8:58: "Most assuredly, I say to you, before Abraham was, I AM." This is the crucial one because "Yahweh" is simply ancient Hebrew for "I am." At the time, there were something like four or five extant claims to being the messiah. But the one guy calling himself Yahweh was considered a blasphemer.
YKVK is more than just I Am, it's the ground of existence, being and becoming to put it in western terms, something none of flesh and blood could claim of themselves. That's getting into theological territory, however.
There is a reason why the other claimants to being the messiah got more Jewish followers, such as Bar Kochba who had many thousands of Jewish followers including Rabbi Akiva shortly after the events depicted in the NT, or Sabbatai Tzvi who had half a million followers in the 17th century CE before his apostacy to Islam. We believe in the Tanakh's description of what the messiah is, and not the author of the Gospel of John, and according to you, what the protagonist of the Gospels said of himself. We have no reason to believe that either our religion changed, or what our scriptures and traditions say the Messiah is, is not the case. There are many good reasons to believe, however, that xtianity is another religion other than Judaism.
After the destruction of the temple by the Romans, Judiasm has had a two-thousand-year identity crisis. Many Jews no longer believe in a moshiach. Others think the moshiach will be just an event, or an idea. A mere concept that will somehow change the world. But in the original Hebrew texts (from before 200 CE, so predating talmudic texts like the mishnah), the moshiach was definitely a person.
I don't wish to be disrespectful, but you are misinformed about Jewish history, and Jewish texts, and overall Jewish belief outside of the Reform and Conservative movements which only began recently and themselves claim to be a "progression" from prior beliefs anyway so they wouldn't disagree with my assessment. The Mishnah and Gemara and all Orthodox Jews (i.e. all Jews until about a hundred and fifty years ago) believe the messiah is a person. Definitely a person, not a deity, or even a mere idea. A person, nearly as great as Moses our Teacher, who will transform the world for good, more than evil men have tried to transform the world for bad in the 20th century and other times.
The belief that he's a mere concept or event that you cite is that of Reform Judaism, not a "2,000 year identity crisis", but from a now almost uniquely American identity crisis. (Originally German, as Reform, was started to combat antisemitism in Germany by making Judiasm less "particular" and more like their more liberal neighbors. That didn't work too well, though before Hitler even in Germany it managed to produce a 85% intermarriage rate.)
I should add that it is your right and privilege to believe otherwise concerning who and what the Torah and prophets and writings teach the messiah is, and I wish you no ill will for having different beliefs than mine. After all, Jews don't believe only Jews get into heaven; so if you follow the 7 laws of Noach you'll be OK, and even if you don't, it is none of my business what you believe or do as long as it doesn't hurt me or others. We believe that all nations except for Amelek will repent when the Messiah comes, and that is when it is proper for non-Jews to change their beliefs to Noachide ones unless they wish of their own free will and persistence to do otherwise beforehand. As we Jews say, Shalom, peace, and I hope nothing I've written has irritated you merely by disagreeing with you, since after all, that's what separates us and the people who will probably execute that poor journalist.
