Since only baptism can give a child certain access to Heaven, the Church teaches the importance of infant baptism for every child. Children in danger of death should be baptized without delay. Catholic parents who neglect or unreasonably put off for a long time the Baptism of their children commit a mortal sin. It would be a mortal sin, for example, to delay or postpone indefinitely the Baptism of a child in order to save-up or prepare for a big feast, a great worldly show, with dances and dinners and what not. Or, to delay the Baptism in order to wait for the coming of a VIP godparent.
None even offers it as a possibility.
They believe that the souls of babies who die before baptism, and some others, are in the presence of God. He based his beliefs on the principle of Predestination. He believed that God decides in advance which individuals will be eternally saved and which will be eternally lost. This was interpreted by some as meaning that there are elect infants who go to Heaven and unelect who go to Hell.
