I'm not wanting to argue, I'm just pointing out one of the items that made me think the whole thing wasn't for me. This response is a fast and half-thought reply; if desired I can go into it more later or answer specific questions.
The passage in question is a take on Matt. 22:34-40 that paints Jesus as the fulfillment of the Old Covenant, and the start of the new one. The New Covenant is much simplified because the laws in the Torah had been turned into confusing mess mess by religious leaders, and had been leveraged in different ways depending on interpretation.
[A Pharisee lawyer] asked him a question, to test him. “Teacher, which is the great commandment in the law?” And he said to him, “You shall love the Lord your God with all your heart, and with all your soul, and with all your mind. This is the great and first commandment. And a second is like it, You shall love your neighbor as yourself. On these two commandments depend all the law and the prophets.”
Another conundrum is that Matt. 5:17-19 clouds the waters:
“Think not that I have come to abolish the law and the prophets; I have come not to abolish them but to fulfill them. For truly, I say to you, till heaven and earth pass away, not an iota, not a dot, will pass from the law until all is accomplished. Whoever then relaxes one of the least of these commandments and teaches men so, shall be called least in the kingdom of heaven; but he who does them and teaches them shall be called great in the kingdom of heaven.”
Further hair-tearing out can happen when the interpretations say that the Jewish people are *STILL* bound by the laws in the Torah, but that they don't apply to Christians. Which is kind of absurd, because only ONE interpretation of faith can be correct if they are the indisputable word of god. I'm not a religious scholar by any means, but it's a topic of lively debate amongst them, with opinions running the spectrum depending on what viewpoint they are trying to support or erode. The word of God shouldn't be contradictory. These contradctions always bothered me.
Viewpoints that I've heard from people where they try to dissect these teachings and through prayer and contemplation delve through the power structures and bullE36 M3 to the heart of the matter *do* tend to agree that living a life according to " You shall love your neighbor as yourself" is probably the most universal and closest to god somebody can get.
In my life, I can do that without any supernatural god(s), tithes, churches and the like. It'll be easy to misinterpret this, but each person is their own god, in that (outside of serious mental illness) they have free will to live their life as close to or as far away from that universal commandment as they wish.
Some fast links I dug up on the subject that probably just begin to touch on how deep the debate can run:
