1306  every baptized person not yet confirmed can and should receive the sacrament of confirmation. since baptism, confirmation and eucharist form a unity, it follows that "the faithful are obliged to receive this sacrament at the appropriate time," for without confirmation and eucharist baptism is certainly valid and efficacious, but christian initiation remains incomplete.
1307the latin tradition gives "the age of discretion" as the reference point for receiving confirmation. but in danger of death children should be confirmed even if they have not yet attained the age of discretion.
