The place and condition of perfect supernatural happiness. This happiness consists essentially in the immediate vision and love of God, and secondarily in the knowledge, love, and enjoyment of creatures. Until the final resurrection, except for Christ and his Mother, only the souls of the just are in heaven. After the last day, the just will be in heaven in body and soul. Although the same God will be seen by all and enjoyed by all, not everyone will have the same degree of happiness. The depth of beatitude will depend on the measure of God's grace with which a person dies, and this in turn will be greatly conditioned by the merits that one earns during life on earth. Heaven is eternal because it will never cease. It is continuous because its joys never stop. It is communal because the happiness is shared with the angels and saints and the company of those who were known and loved on earth.
