I think we have discussed this before, but I also think it's worthy enough for a second go round--
I've done more thinking since then.
I offer up this quote from the Bible:
"If they have escaped the corruption of the world by knowing our Lord and Savior Jesus Christ and are again entangled in it and overcome, they are worse off at the end than they were at the beginning. It would have been better for them not to have known the way of righteousness, than to have known it and then to turn their backs on the sacred command that was passed on to them." 2Peter 2:20,21
I went and found that because it reminded me of that little story I'd read somewhere, regarding a missionary who traveledthroughout Africa. He taught the scripture and redemption, via Jesus Christ, as he understood it to some of the "heathen" tribes that still worshiped multiple nature Gods and Goddesses.
When he had done this, he was asked by a tribal leader, pretty much the same question you ask, and answered with the same quote I offer you above.
The tribal leader was incredulous. He took his time though, and asked, that if ignorance was safety:
"Why then, did you tell me?"
I'm no longer as sure as I once was if ignorance is bliss--ignorance can be painful, if not fatal when a levee breaks.
Also--I just spoke to a buddy, who spoke to me about Catholic belief regarding "Age of Reason." Apparently, babies and little children are safe from eternal damnation until the age of seven, after they have received proper instruction in catechism, made confession, and received Holy Communion.
And yes, I asked him why the emphasis on the rite of "christening".
He said it was to wash away the original sin of flesh.
(I'm confused too.)
I guess it is kind of like extra insurance?
Feel free to enlighten me, 'cause I am puzzled too.
