[Cronos]

Also, your statement on Limbo is historically and utterly wrong. In the Middle Ages theologians came up with the theological construct of limbo, which never has been a defined doctrine. Limbo does get around two sticking points: the absence of sanctifying grace, which implies no possibility of heaven, and the absence of personal guilt, which implies no hell. Unbaptized infants die with neither, so it might seem that they are destined neither for heaven nor hell.

the theory of limbo has never been a defined doctrine of the Church, the Church has never rejected it. The official teaching of the Church on the fate of unbaptized children is found in the Catechism:

"As regards children who have died without baptism, the Church can only entrust them to the mercy of God, as she does in her funeral rites for them. Indeed, the great mercy of God who desires that all men should be saved and Jesus’ tenderness toward children, which caused him to say, ‘Let the children come to me, do not hinder them,’ allow us to hope that there is a way of salvation for children who have died without baptism. All the more urgent is the Church’s call not to prevent little children coming to Christ through the gift of holy baptism" (CCC 1261).

What does Calvin say? He says that those unborn, unbaptised "elect" babies go to heaven. Does this mean that those killed in abortions are all, according to Calvin, "elect"? Does Calvinism them logically say that it should be wiser to "kill 'em all" since that would make them elect and go straight to heaven?

Now THAT is satanic

No, you just said it.

Now THAT is satanic

Then stop saying it.

Yes, some theologians did and those theologians were wrong.

Neither Christ nor the apostles taught the concept of limbo and the early church didn't believe it.

Rome pretends.

Discernment.
