Has organised Christianity been detrimental?

[TevashSzat]

I agree with the Don about man having a negative impact on Christianity. If I were a believer in the Christian God, I would recognise that Christianity is inseparable from the church, meaning that Christianity was organised from the onset. If I was a believer in the God of Abraham, Isaac and Jacob and that Jesus Christ was his only begotten in the flesh, I would believe the Bible being a true record of how God told his people to live and worship.

My memory of world history might be a bit rusty, but didn't Jesus not formally organize Christianity? Isn't it his disciples who did it after his death so in a sense, Christianity would be a religion created by man. Its principles may be based off of (supposedly) divine principles, but Jesus was considered a Jew until his death.

Thus, in a sense, Man can't have a negative impact on Christianity if it was first created by man
