Limbo is a theological concept in Christianity, particularly in Catholicism, referring to a state of existence for souls who have died without being baptized but are not condemned to hell. It is often associated with the souls of unbaptized infants and righteous individuals who lived before the coming of Jesus Christ. Limbo is not an official doctrine but has been a topic of discussion among theologians. In recent years, the Catholic Church has shifted its stance on Limbo, emphasizing God's mercy and the hope of salvation for all souls. The 2007 document from the International Theological Commission suggested that unbaptized infants may be entrusted to God's mercy, moving away from the traditional view of Limbo as a permanent state.
