Holy Sealing is the sacrament through which the believer, through the laying on of hands and the prayer of an Apostle, receives the gift of the Holy Spirit and becomes a child of God with the calling to become a firstling. Accordingly, the Eighth Article of Faith states: "I believe that those baptised with water must, through an Apostle, receive the gift of the Holy Spirit to attain the childhood in God and thereby the prerequisite for becoming a firstling."
