@Link's thread.
Why did you, if you did, reject Jesus? Why did you disagree with his claims and/or the claims made for him?
I don't think I "reject" Jesus, even on the basis that an historical Jesus existed.
The prevailing story in the four gospels is that God put [his] "son" Jesus on earth to carry out a suicide mission (in the sense that its purpose was Jesus' unnatural death). Thus Jesus says as much in Mark 2:20 (earliest of the gospels) and all four gospel versions of Jesus, knowing that death is threatened, refuse the chance to escape because God doesn't want him to escape.
Thus Jesus is crucified, and as a result in some unexplained sense those who "believe" are "forgiven" their "sins" and qualify for "everlasting life" (a phrase which Paul interprets as putting on an incorruptible and immortal spiritual body, and John perhaps implies means "being one with God" whatever those mean).
Why, once God has sacrificed [his] son to [him]self, you have to believe anything to get the benefit is unexplained and appears to be simply a recruitment bait. It's inconceivable that a god who would do this would at the same time be called "benevolent" and "omnipotent" (and certainly reinforces the formula attributed to Epicurus).
According to all three synoptics, the Son of Man (inferentially but not expressly Jesus) will return in the lifetime of some of Jesus' audience and set up the Kingdom of God on earth. By the time John was written this was looking rather silly, and was dropped; but it was central to the Christian message at its inception. That the world would be better off ruled by one autocrat who can't be removed from office sounds like Donald's Dream to me.
Oh, and Jesus said, or others said on his behalf, that we should love one another, a message that no doubt accounts for the long history of internecine wars between Christian factions and nations, the longer history of murderous Christian antisemitism, the ruthlessness of the colonialism of European nations, and the existence of hundreds if not thousands of sects of Christianity.
So like the pea under the cups, now you see it, now you don't, but you know it's rigged. And that leaves me unclear as to what about Jesus is specific enough to reject.
Just to be clear, I have no argument with moderate Christians; various of my close friends and dear relatives are believers. My suspicion is that if you treat others with decency, respect and inclusion, then it doesn't matter what you believe, and you'll depart this life leaving the world no worse, and maybe better, than you found it.
