Traditional Christianity is dying. But there's a progressive movement within it that I think has a good chance to salvage something worthwhile from the traditional version.
With some careful tweaking, Jesus can be presented as an exemplar, what the human character ought to be, useful for Christians and non-Christians, whether he was fictional or not.
Jesus will have to love unconditionally because conditional love (I will love you if you please me) is a lesser kind of love that arrogant people offer as a manipulative device to coerce compliance with their wishes.
Jesus won't be presented as a front man for an unjust, vengeful god that loves conditionally (accept the Christian doctrine or you will go to Hell). Instead, Jesus will offer an example for people who strive to become better human beings as their only form of worship.
That reformation might needs extensive effort to modify the Bible. Remove all the bad but good teachings; thoroughly rewrite the Bible to speak what it intends to convey in a straight forward and modern language manner; avoid any ambiguity; made it clear if any passages is not to be read literally and unambiguously explain what they actually mean in the footnote.
What is the precise goal this new denomination of Christianity intended to achieve?
What is the precise method it use to achieve its goal?
What is the precise requirement to qualify "Jesus have been save by this new denomination"?
Jesus can't be presented as a pacifist. Consider this rabid dog analogy: We see a rabid dog in the street and recognize it as a danger both to human and animal life, so we have to kill it. We regret that the killing was necessary. The only thing we hate is our ignorance in not knowing how to cure rabies. The killing was an act of love for humanity and for other animals. Jesus would see the necessary killing of dangerous human beings in self-defense as ultimately an act of love for humanity.
The new denomination need to lay out all the precise requirements how they qualify a creature to be dangerous which they think they have no choice but to kill those dangerous creatures, so all people who want to thoroughly examine those requirements can do so.
Do the new denomination also intend to policy their versions of self-defence law into the country or globally and upon non-member of their religion?
Jesus would hate the sin but love the sinner. Consequently, he would see the wrongdoer as sick not evil. Thus, progressive Christians will advocate quarantine and not punishment for offenders. For example, child molesters might be sent to an adult-only town for life or until cured, even on a mild first offense. There, they could live and work normally but without access to children. The result would be a safer world for children.
Please lay out the complete list of crimes if you suggest they should be exempt from punishment.
Do paedophile who voilentlly sexually abuse 100+ children also be exempt from punishment? What is the line and qualification whether or not an offender should be exempt from punishment?
What kind of towns do we use to respectively quarantine thiefs, drunk driver, spy, con artist fraud, forger, briber, blackmailer, burglar, kidnapper, terrorist, traitor, arsonist, assassin, bomber, murderers and genociders...etc?
