I think it all boils down to Leviticus 19:18 וְאָהַבְתָּ לְרֵעֲךָ כָּמוֹךָ V'ahavta l'reiacha kamocha "Love your neighbor as yourself." The question is, who is my neighbor. Rei’a is broader than just someone who lives next door. I wont' lie to you. There are some Jewish Rabbis who say that this verse is referring to the Jewish people. But there are also Rabbis who say that this refers to all of humanity. Their argument is based on the fact that this word, Rei'a, is used elsewhere in the Torah where it clearly is NOT referring to the Israelites.
For example, Exodus 11:2 דַּבֶּר־נָא בְּאָזְנֵי הָעָם וְיִשְׁאֲלוּ אִישׁ מֵאֵת רֵעֵהוּ..."Let every man ask from his neighbor (rei'eihu)... silver and gold" Here, the "neighbors" are Egyptians--clearly non-Israelites. So rei’a must include non-Jews.
Ramban (Nachmanides) explains that while the Torah may have begun with obligations to one’s own community, the ethical ideals are meant to grow into universalism.
Now we can move to discuss what "love" means. It doesn't not mean unconditional approval of everything the other does. It means wanting what is in their best interest. I'm sure you have heard the term "tough love." Holding our enemies accountable for the harm they do is not hatred. It is treating them with dignity owed every human being by holding them responsible for their wrong.
Yes, I think I generally empathize with what you're sharing here and reflecting upon from various Jewish rabbis.
However, Christians will usually refer to the specific teachings of the New Testament writers since those writers express what they believe is their own report about what Jesus of Nazareth taught. So, in the case of "loving even one's enemies," there are implied nuances in the texts that go beyond what the Jewish rabbis might be teaching in various forms of Judaism. I'm not saying that Jewish people never have willingness to be generous and go extra miles for other people. I'm sure that some of them, like some Gentiles, may very well do so. But, I'm also essentially aware of the Jewish perspectives, historically and politically considered, such as would be seen in the following works as but a few examples I can provide:
Rabbi Milton Steinberg - Basic Judaism
Stuart E. Rosenberg - The Christian Problem
Michael Goldberg - Jews and Christians, Getting Our Stories Straight
Paul J. Kirsch - We Christians and Jews
Rabbi Yechiel Eckstein - What Christians Should Know About Jews and Judaism
One brief example is seen in Jesus' admonition to His disciples that "if someone forces you to go one mile [such as the Romans would conscript Jewish civilians to do from time to time back in the 1st century], ... go with them TWO miles." Not many people are willing to follow through and attempt such supererogation today by going a second mile, or maybe a third one, especially among those of us living in a post-Revolutionary Age who are told that "revolting against apparent injustice" is fully justified where any individual perception of human rights violations is present.
Likewise, another often quoted bit of New Testament regarding how Christians see the nature of "love"----and whether or not Christians today actually live up to the standard placed before them nearly 2,000 years ago----is seen in Paul's teaching in 1 Corinthians 13:1-8, with particular emphasis placed on the use of verses 4 to 8.
Not to worry. We are both getting to know each other.
I also tend to be misunderstood. My ideas are always highly nuanced. For the sake of clarity and easy reading on a forum, I simplify. But in doing so, the complexity of what I really think is lost. Someone can read one post here, and another post there, and scratch their head because I seem to be contradicting myself, when in actuality, each post is a piece of a much larger puzzle.
Don't worry about it. I understand you.
I think that's wonderful!
My own degree is in Liberal Studies (a "liberal" dose of all subjects lol) because when I look out on the world, I see how everything is interconnected with everything else.
And I value your academic work you've done, and it sounds like you and I have some similarity in our respective research approaches.
But I have to admit, I do have a particular fondness for Ethics, Religion, and Psychology. I've only ever taken one philosophy course (Logic and Critical Thinking) so my credentials don't come from study, and in some ways you will leave me in the dust LOL. My credentials come from my intense introspection, turning ethical issues over and over again in my mind.
I'm sure you have some interesting points to make, then, being that you're an informed reflector.
