Why has the golden rule failed?
nope you have your interpretation and the bible the source of both eye for eye and what you call the golden rule state what they state
the source is the correct interpretation because its according to the source. if you are going to use what Jesus says then you must use all of what Jesus says. and according to the bible Jesus is the Word of God made flesh and it was the Word of God that spoke the law of eye for an eye to Moses, and it was also the same source, the Word of God, that spoke the golden rule, isn't it?
and according to the bible God doesn't change. so the golden rule is not without the eye for an eye rule. and the eye for an eye rule is not without the golden rule. or you miss understand the One who spoke it.
and actually the golden rule is how to live in a society that is an eye for an eye rule.
if you don't believe all of what the bible says, then why use it to justify your own judgement, unless you are out to deceive those who believe it but don't know it very well.
go by your own rules and be honest about it.
also forgiveness isn't an entitlement or its not forgiveness. so forgiveness isn't assumed only available if granted by the injured party the one who has the power to forgive. what is agreed.
if Jesus speaks a commandment like the "golden rule" its law, for those bond to it. if your not bond to it what does it matter to you? Jesus to the faithful is the everlasting covenant, also meaning agreement or contract. therefore all that He says is law to those in the Kingdom of God that He preached. also Jesus says He didn't come to eliminate the law (Torah) He came to fulfill it. so the law isn't null and void as many want to believe.
how did Apostle Paul say it:
Do we then make void the law through faith? God forbid: yea, we establish the law.
