How did Hitler and his nazis discriminate as to who was a "jew" and who wasn't? By "jewish" last names or "jewish" bodily features? Membership in a synagogue or "jewish-sounding" association? Government-questionnaire answers? Maybe a combination of all such, so as to know who to force the wearing of Star of David lapels and assemble into concentration camps such as Auschwitz, Dachau, and Buchenwald.

Clearly, der Fuehrer should have given jews more time to become Evangelical or Catholic Christians rather than cutting their opportunity short by gassing and burning them in concentration camp ovens first, and should have known that salvation for humankind was not from imaginary "aryans" but instead:

John 4:22 You worship what you do not know; we worship what we know, for salvation is from the Jews (or as the Germans and Greeks would say: Juden).

There is gross (and intrinsically antisemitic!) misunderstanding mouthed by some about when and why jews were first called "Jews." The following Scripture verses from the Jewish Old Testament itself plainly and logically indicate that neither belonging to Judah (as only one of the 12 Tribes of Jacob/Israel)....nor temporarily residing in or re-location to the territorially-limited land of Judea......is basis for origin of the word "Jew" regarding EITHER the ancients OR New-Testament "Jews:"

Second Kings 25:25 But in the seventh month, Ishmael the son of Nethaniah, son of Elishama, of the royal family, came with ten men, and attacked and killed Gedaliah and the Jews and the Chaldeans who were with him at Mizpah.

Esther 1:1 In the days of Ahasuerus, the Ahasuerus who reigned from India to Ethiopia over one hundred and twenty-seven provinces,
2:5 Now there was a Jew in Susa the capital whose name was Mordecai, the son of Jair, son of Shimei, son of Kish, a Benjaminite,
3:6 But he disdained to lay hands on Mordecai alone. So, as they had made known to him the people of Mordecai, Haman sought to destroy all the Jews, the people of Mordecai, throughout the whole kingdom of Ahasuerus.
8:9 The king's secretaries were summoned at that time, in the third month, which is the month of Sivan, on the twenty-third day; and an edict was written according to all that Mordecai commanded concerning the Jews to the satraps and the governors and the princes of the provinces from India to Ethiopia, a hundred and twenty-seven provinces, to every province in its own script and to every people in its own language, and also to the Jews in their script and their language.

Sadly, there is an obvious denial of real and bonafide "jewishness" among many, including antisemitic cultic educrats and some so-called "intellectuals" besides certain Israel-hating government leaders here and especially abroad. For instance, A-mini-jihad (as I aptly term him) shrewdly does not deny the Holocaust of the 1940s, but instead relentlessly questions it and all archived proofs relating to that.

Some would presume that alleged-"jewish" rituals (religious or non-religious) comprise "jewishness" -- such as categorizing some things as "kosher" or not, eating matzo-ball soup and gefilte fish, doing passover seders, wearing black hats and coats with pigtailed hair, sporting nine-candled menorahs, and bobbing forward and backwards at the Wailing Wall which antisemitic Herod built.

Some would even go so far as to include mandatory hand-washing, not eating pork nor pork products, talking Yiddish, and getting circumcised as ultimate proof of being "jewish:"

Matthew 15:1 Then Pharisees and scribes came to Jesus from Jerusalem and said,
2 "Why do your disciples transgress the tradition of the elders? For they do not wash their hands when they eat."
3 He answered them, "And why do you transgress the commandment of God for the sake of your tradition?
4 For God commanded, 'Honor your father and your mother,' and, 'He who speaks evil of father or mother, let him surely die.'
5 But you say, 'If any one tells his father or his mother, What you would have gained from me is given to God, he need not honor his father.'
6 So, for the sake of your tradition, you have made void the word of God.
7 You hypocrites! Well did Isaiah prophesy of you, when he said:
8 'This people honors Me with their lips, but their heart is far from Me;
9 in vain do they worship Me, teaching as doctrines the precepts of men.'"
10 And He called the people to Him and said to them, "Hear and understand:
11 not what goes into the mouth defiles a man, but what comes out of the mouth, this defiles a man."
19 For out of the heart come evil thoughts, murder, adultery, fornication, theft, false witness, slander, (withholding tithes?).
20 These are what defile a man; but to eat with unwashed hands does not defile a man."

Notice that in the list Jesus did not include "jewish" health rules of bathing after seminal emission and menstruation, not boiling a kid in it's mother's milk, building another tabernacle according to the exact specs in the Torah, etc. etc. etc.

Whether good or bad, jews as a whole are:

Romans 3:2 ....entrusted with the oracles of God.

When it comes to those 'oracles of God,' Jesus command us to:

Matthew 23:3 so practice and observe whatever [the Pharisees] tell you, but not what they do; for they preach, but do not practice.

.....but obey God rather than humans when it comes to mere purported "jewish" traditions and human regulations:

Colossians 2:11 In him also you were circumcised with a circumcision made without hands, by putting off the body of flesh in the circumcision of Christ;
13 And you, who were dead in trespasses and the uncircumcision of your flesh, God made alive together with Him, having forgiven us all our trespasses,
14 having canceled the bond which stood against us with its legal demands; this He set aside, nailing it to the cross.
15 He disarmed the principalities and powers and made a public example of them, triumphing over them in Him.
16 Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath.
18 Let no one disqualify you, insisting on self-abasement and worship of angels, taking his stand on visions, puffed up without reason by his sensuous mind,
19 and not holding fast to the Head, from whom the whole body, nourished and knit together through its joints and ligaments, grows with a growth that is from God.
20 If with Christ you died to the elemental spirits of the universe, why do you live as if you still belonged to the world? Why do you submit to regulations,
21 "Do not handle, Do not taste, Do not touch"
22 referring to things which all perish as they are used), according to human precepts and doctrines?
23 These have indeed an appearance of wisdom in promoting rigor of devotion and self-abasement and severity to the body, but they are of no value in checking the indulgence of the flesh.

It is clear that there are currently both good and evil jews. Interestingly enough, Saint Paul reminds us in Romans chapter 9 through 11 and Galatians chapters 2 through 4 [and PLEASE read them thoroughly!] that some bad jews can and will eventually become good Jews. Either way, both types retain that aspect of "jewishness" related to blood-descendancy from Hebrew (and also Jewish!) patriarchs Abraham, Isaac, and Jacob (also called "Israel")!

Romans 11:23 And even the [temporarily bad jews], if they do not persist in their disbelief, will be grafted in, for God has the power to graft them in again.
24 For if you have been cut from what is by nature a wild olive tree, and grafted, contrary to nature, into a cultivated olive tree, how much more will these natural branches be grafted back into their own olive tree.
25 Lest you be wise in your own conceits, I want you to understand this mystery, brethren: a hardening has come upon part of Israel, until the full number of the Gentiles come in,
26 and so all Israel will be saved; as it is written, "The Deliverer will come from Zion, he will banish ungodliness from Jacob"
27 "and this will be my covenant with them when I take away their sins."
28 As regards the gospel they are enemies of God, for your sake; but as regards election they are beloved for the sake of their forefathers.
29 For the gifts and the call of God are irrevocable.

As Moses was qualified to write the first five books of the Old Testament because of his oral Jewish traditions learned from his day-care original mother and family and because of the best-possible royal Egyptian higher-education provided by Pharoah's daughter, so the High-Master 33rd-degree Pharisee Saul-turned-Paul (a.k.a. bad jew turned good Jew) was qualified to write almost half the New Testament.

And how does that master-Jew Saint Paul (though of course not THE Master-Jew Jesus) -- both authentic and genuine blood-descendant Hebrew Israelites of the tribe of Judah and Benjamin respectively according to the geneologies of Matthew chapter 1 and Luke chapter 3 -- define: "true Jews?"

Romans 2:23 You who boast in the law, do you dishonor God by breaking the law?
24 For, as it is written, "The name of God is blasphemed among the Gentiles because of you."
25 Circumcision indeed is of value if you obey the law; but if you break the law, your circumcision becomes uncircumcision.
26 So, if a man who is non-circumcised keeps the precepts of the law, will not his non-circumcision be regarded as circumcision?
27 Then those who are physically non-circumcised but keep the law will condemn you who have the written code and circumcision but break the law.
28 For he is not a real Jew who is one outwardly, nor is true circumcision something external and physical.
29 He is a Jew who is one inwardly, and real circumcision is a matter of the heart, spiritual and not literal. His praise is not from men but from God.

Of the aforementioned, blood-descendant Jews are described prophetically:

Revelation 7:5 twelve thousand sealed out of the tribe of Judah, twelve thousand of the tribe of Reuben, twelve thousand of the tribe of Gad,
6 twelve thousand of the tribe of Asher, twelve thousand of the tribe of Naphtali, twelve thousand of the tribe of Manasseh,
7 twelve thousand of the tribe of Simeon, twelve thousand of the tribe of Levi, twelve thousand of the tribe of Issachar,
8 twelve thousand of the tribe of Zebulun, twelve thousand of the tribe of Joseph, twelve thousand sealed out of the tribe of Benjamin.

Again, previous temporary location inside or outside of "Judea" was and is quite irrelevant in terms of defining those "Jews" -- as previous temporary location of Greek or Somalian or Hispanic/Mexican or Swedish people is quite irrelevant in terms of defining those ethnic cultural groups.

"Bad jews" are exposed with:

Revelation 2:9 I know your tribulation and your poverty (but you are rich) and the slander of those who say that they are Jews and are not, but are a synagogue of Satan.
9 Hey, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie -- hey, I will make them come and bow down before your feet, and learn that I have loved you.

And example of a bad jew was Esau and a good Jew was Jacob - the latter of whom realized the value is acquiring and possessing the birthright promise of faith in and of the LORD, whereas godless and faithless Esau saw no value in such and exchanged it for immediate temporary-gratification pottage:

Hebrews 12:15 See to it that no one fail to obtain the grace of God; that no "root of bitterness" spring up and cause trouble, and by it the many become defiled;
16 that no one be immoral or irreligious like Esau, who sold his birthright for a single meal.
17 For you know that afterward, when he desired to inherit the blessing, he was rejected, for he found no chance to repent, though he sought it with tears

A little backround:

Genesis 25:32 Esau said, "I am about to die; of what use is a birthright to me?"
34 Then Jacob gave Esau bread and pottage of lentils, and he ate and drank, and rose and went his way. Thus Esau despised his birthright.

Later on, according to Genesis chapter 27, Jacob lied in pretending to be birthright-despiser Isaac to get his father's blessing (again, a thing of faith relating to the LORD and His promises). Even though conniving Jacob was dishonest in the process, the end justified the abhorrent and noxious means, and was done because Esau did not deserve such a blessing, being the kind of a bad jew he was. And to show how bad that bad-jew Esau was, he defamed his father by deliberately marrying Canaanite (Cain-like) wives, which is something Isaac told Jacob's matchmaker to never do regarding his son Jacob:

Genesis 24:37 My master [Isaac] made me swear, saying, 'You shall not take a wife for my son [Jacob] from the [idols-worshipping] daughters of the Canaanites, in whose land I dwell;

Genesis 28:8 So when Esau saw that the Canaanite women did not please Isaac his father,
9 Esau went to Ishmael and took to wife, besides the wives he had, Mahalath the daughter of Ishmael Abraham's son, the sister of Nebaioth.

Genesis 32:3 And Jacob sent messengers before him to Esau his brother in the land of Seir, the country of Edom,

Genesis 36:1 These are the descendants of Esau (that is, Edom).
2 Esau took his wives from the Canaanites: Adah the daughter of Elon the Hittite, Oholibamah the daughter of Anah the son of Zibeon the Hivite,
4 And Adah bore to Esau, Eliphaz; Basemath bore Reuel;
5 and Oholibamah bore Jeush, Jalam, and Korah. These are the sons of Esau who were born to him in the land of Canaan.
6 Then Esau took his wives, his sons, his daughters, and all the members of his household, his cattle, all his beasts, and all his property which he had acquired in the land of Canaan; and he went into a land away from his brother Jacob.
8 So Esau dwelt in the hill country of Seir; Esau is Edom.

God's curse because of bad-jew Esau's flagrant godlessness and faithlessness had dire far-reaching future consequences:

Obadiah 1:6 How Esau has been pillaged, his treasures sought out!
8 Will I not on that day, says the LORD, destroy the wise men out of Edom, and understanding out of Mount Esau?
9 And your mighty men shall be dismayed, Teman, so that every man from Mount Esau will be cut off by slaughter.
18 The house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau stubble; they shall burn them and consume them, and there shall be no survivor to the house of Esau; for the LORD has spoken.
19 Those of the Negeb shall possess Mount Esau, and those of the Shephelah the land of the Philistines; they shall possess the land of Ephraim and the land of Samaria and Benjamin shall possess Gilead.
21 Saviors shall go up to Mount Zion to rule Mount Esau; and the kingdom shall be the LORD's.

Malachi 1:2 "I have loved you," says the LORD. But you say, "How have You loved us?" "Is not Esau Jacob's brother?" says the LORD. "Yet I have loved Jacob
3 but I have hated Esau; I have laid waste his hill country and left his heritage to jackals of the desert."

Romans 9:13 As it is written, "Jacob I loved, but Esau I hated."

Hebrews 11:20 By faith Isaac invoked future blessings on Jacob and Esau.

But eternal blessings are only for those who voluntarily love and obey Christ!

One final definition of a bad jew:

First John 2:22 Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son.

Why?

Proverbs 30:4 Who has ascended to heaven and come down? Who has gathered the wind in His fists? Who has wrapped up the waters in a garment? Who has established all the ends of the earth? What is His name, and what is His Son's name? Surely you know!

And for those who want crucial "Change!" in 2010, it behooves them to remember and comply with the following:

Isaiah 3:12 My people: children are their oppressors, and women rule over them. My people, your leaders mislead you, and confuse the course of your paths.
Nahum 3:13 Hey, your troops are women in your midst. The gates of your land are wide open to your enemies; fire has devoured your citadels.

I Timothy 2:5 For there is one God, and there is one mediator between God and men, the man Christ Jesus,
6 who gave himself as a ransom for all, the testimony to which was borne at the proper time.
8 I desire then that in every place (like political rallies and demonstrations) the men should pray, lifting holy hands without anger or quarreling;
9 also that women should adorn themselves modestly (e.g. ponytail, sleeves, slacks, socks) and sensibly in decent apparel (especially during warm weather), not with plaited hair or gold or pearls or costly attire
10 but by good deeds, as befits women who profess religion.
11 Let a woman learn in silence with all submissiveness.
12 I allow no woman to teach or to have authority over men (as newscasters, judges, cops, etc.); she is to keep silent.
13 For Adam was formed first, then Eve;
14 and Adam was not deceived, but the woman was deceived and became a transgressor.
15 Yet woman will be saved through bearing children, if she continues in faith and love and holiness, with sobriety.
