This theory, elaborated by theologians beginning in the Middle Ages, never entered into the dogmatic definitions of the Magisterium, even if that same Magisterium did at times mention the theory in its ordinary teaching up until the Second Vatican Council. It remains therefore a possible theological hypothesis. However, in the Catechism of the Catholic Church (1992), the theory of limbo is not mentioned. Rather, the Catechism teaches that infants who die without baptism are entrusted by the Church to the mercy of God, as is shown in the specific funeral rite for such children.
