The Magisterium of the Church has confirmed throughout
centuries the eternal lot of all souls, either in heaven, purgatory
or hell is decided once for all at the moment of death.
January 29, 1336,
"We define that the souls of all the saints who have left this life
soon after individual death are or will be in heaven and have
eternal life; in addition we define that the souls of those dying
in actual mortal sin soon after individual death descend into hell."
