Anointed 1,
You say that a 'person who doesn't believe in God has no obligation to care for anyone,' which I think is an unfair judgment. I find many of my atheist friends, especially ones here, who consider caring for their neighbor a serious obligation. One does not have to have a belief in God to be moral, just, or feel obligated for caring for their community and making the world a better place. Some of history's best examples of this are atheists and agnostics.
I think some here, including myself, a Jew, might see this as stereotyping. That's an unfair use of labels, don't you think. Just the other day I saw Simon, the man who runs this board, do something very caring, moving and brave on this site because he obviously has an innate sense of honor for caring for others. He doesn't believe in God, but rest assured I don't think he or other atheists like him think this somehow makes them without obligation.
I also think you are judging things from a Christian perspective. I wouldn't say that what I do as a Jew constitutes a "belief" in God. Beliefs are the holding of a static concept in the mind, often abstract, a mental assent to a particular concept without doubt required of Christians to belong to their particular denominations. As a Jew I have to agree with James on this one: "You believe in God, you say? All well and good. But so do demons, though the thought scares them."--James 2:19.
Beliefs in of themselves are not always beneficial, though people fight over them as if they were money. Who says that people who believe in God have a responsibility to care for others? Does it mastter? It's just another belief, a mental spark, that a person can fulfill or fail to live up to. So what if a theist doesn't live up to their beliefs? Beliefs are not tangible. If your belief doesn't move you to act accordingly under test, what good is assent to a mental concept, a definition someone demands that you agree to hold onto in your head?
What people accomplish is what matters. Everyone fails, regardless of those "beliefs" so many feel are so important. True, they can and should inspire a person to do good, but again beliefs are static. Holding onto a belief is not the same as doing something like living up to it.
Belief in a God is a label. You cannot prove that your mental assent to this concept is being grasped exactly as necessary to meet the criteria set by some theologian. Disbelief in God is just as intangible. Neither mental concept can gift a person with abilities to do good or bad. Can an atheist guarantee that they disbelieve in God as much as necessary to truly count as an atheist? Can Christians guarantee that they really believe in something like the Trinity accurately enough and complete enough to warrant membership and avoid excommunication?
A Christian might place an obligation upon themselves to care for their neighbor and not live up to it. So? Didn't they themselves place this obligation upon themselves? Even if this obligation really came down from Heaven, didn't they still personally agree to place this obligation upon themselves? Placing an obligation upon oneself, even one that comes from a deity, is no guarantee that you can live up to it.
Now I am a Jewish, someone with a religion. Obviously your belief that "religionists" act or fail to act a certain way doesn't apply to all people with a religion. If all religionists were the same I wouldn't be writing any of this. Because of my religious upbringing I take the stand that it is humanity that commits the failure, not the beliefs or lack thereof. These beliefs or non-beliefs are just labels people often hide behind or proudly wear or use as an excuse to judge others. The common denominator is the human behind the belief or non-belief.
So just answer me this: Does anyone have to have a message from Heaven to be obligated to care for their neighbor and are religionists the only people who fail at this?
