>You don't know that. And anyone who taught you that didn't know either. They're just as in the dark as you are, despite their psychopathic confidence in catechizing people. Not even church fathers and saints were of one mind and sure of it. And all Orthodox to this day pray for departed infants in such a state (it'd be pointless to pray if this fate was a reliable teaching).
You are not in a position to attack clergymen and call them "psychopatic".
Christ Himself tells us that Baptism is necessary for salvation, while the Fathers tell us that original sin condemns one to Hell and only Baptism can cure it. See canon 110 of the Council of Carthage of 419, which was ratified with ecumenical authority by the Council in Trullo:
>Likewise it seemed good that whosoever denies that infants newly from their mother's wombs should be baptized, or says that baptism is for remission of sins, but that they derive from Adam no original sin, which needs to be removed by the laver of regeneration, from whence the conclusion follows, that in them the form of baptism for the remission of sins, is to be understood as false and not true, let him be anathema.
>For no otherwise can be understood what the Apostle says, "By one man sin has come into the world, and death through sin, and so death passed upon all men in that all have sinned", than the Catholic Church everywhere diffused has always understood it. For on account of this rule of faith (regulam fidei) even infants, who could have committed as yet no sin themselves, therefore are truly baptized for the remission of sins, in order that what in them is the result of generation may be cleansed by regeneration.
Infants are baptized for the remission of sin, because even if they have no actual sin, they are born with original sin, which means they are submitted to a tendency to sin, corruption, illness, suffering, death, and Hell.
I'm not a Catholic, thankfully.
By the way, I do know that St Gregory of Nyssa does not think that unbaptized infants go Post too long. Click here to view the full text.
