Cyprian (Carthage, 200 - 258)
wrote of the necessity of the sacrament and
distinguished it from baptism and spoke of it
as a complement to baptism.
 
A local church Council (at Illiberitanum, 300) stated the rite of
administration of confirmation.
                                 Pope Innocent I (401 - 417) taught
       the same rite of confirmation.
 
Jerome (Stridon, modern Slovenia, 345 - 419)
asserted the custom of the Church that priests
and deacons baptize; that bishops confer the
Holy Spirit.
