Once more three liturgical acts were joined to baptism: another anointing, the making of the sign of the cross, and the imposition of hands, of which the last was accounted as the most important. Already in the times of Jerome it was reserved in the West for the bishop, who would frequently perform it in a special room, the consignatory. Since the impartation of the Holy Spirit (Acts 8 and 19) and of His gifts (Is. 11,2) was imputed to such anointing and imposition of hands (beginning of “confirmation”), these supplementary acts were soon accounted as of great importance than baptism itself.
