The choices you give in your survey are very cute.
Yes, there is a Limbo. There must be, due to Original Sin theology. The only reason why there is debate about Limbo is that few comprehend Original Sin theology with clarity.
The “bottom line” of Original Sin theology is that before the action of the grace won by Christ on the cross, we are each of us inherently alienated from God, and “untouchable” to Him. We are “dirty,” so to speak. Free will Man, uninspired by grace, is a sensuous, self-seeking pig. This is what babies are. Babies are inherently ineligible for Heaven.
When Christ died on the cross, He purchased the grace we need to get to Heaven. Baptism is a “grace conduit.” For babies, with an inactive free will, so that Actual Grace can not be accepted by the free will, Baptism is the only grace conduit.
If they die unbaptized, babies simply lack “touchability” in God’s eyes.
Since God is not unjust, He’s not going to send unbaptized babies to that Bedlam of crazed selfish grace rejecters we call “Hell.”
There has to be a better place for morally-innocent-but-“untouchable”-pre-baptized babies.
So, yes, there is a Limbo.
