CCC 1306

Every baptized person not yet confirmed can and should receive the sacrament of Confirmation.¹²¹ Cf. CIC, can. 889 # 1. Since Baptism, Confirmation, and Eucharist form a unity, it follows that "the faithful are obliged to receive this sacrament at the appropriate time,"¹²² CIC, can. 890. for without Confirmation and Eucharist, Baptism is certainly valid and efficacious, but Christian initiation remains incomplete.
