Yes original sin is one of the more pernicious doctrines of Christianity.

Here's a snippet of an old hymn:

"There is a fountain filled with blood
Fed from Emmanuel's veins
And sinners washed beneath that flood
Lose all their guilty stains."

Now there's a "two-fer": Original sin ("guilty stains" -- out, damned spot!) combined with blood sacrifice. Just imagine being washed in a flood of human blood and finding the outcome preferable to imaginary "guilty stains" and you get an idea of how awful this doctrine is.

Ive said it before , so I,ll say it again the only original sin possible is pineapple on pizza.
