ISB ~ Acts 8 v16

not yet fallen:A distinction is made in Acts between Baptism, which confers the Spirit in an invisible way (2:38), and the laying on of hands, which calls down the Spirit to manifest his presence in a visible and charismatic way (19:6).

• In the interpretive tradition of the Church, this deeper conferral of the Spirit through the imposition of hands is linked with Confirmation, a sacrament that follows Baptism and is integral to the process of Christian initiation. As in this episode, deacons (Philip) can baptize, but it belongs to the bishops (Peter and John) to bestow a fuller measure of the Spirit on the baptized by the laying on of hands (CCC 1288, 1313).
