My one and only quibble with the text is the use of the expression “adult, mature Christians” when describing Confirmation. “Confirmation makes us perfect Christians, that is adult, mature Christians.” I think this terminology can lead to misunderstanding about this sacrament. The text does go on to explain that “Confirmation, therefore, by its very nature, ought to be celebrated before the Eucharist, that is, before First Communion. However, for serious pastoral reasons, in many countries it is celebrated later in order to assure adolescents a longer religious formation.”
I think the expression “adult, mature Christians” creates confusion because people think the child needs to choose this sacrament as a sign of adulthood, instead of spiritual maturity. Also, in the Eastern Rites the child does not even need to be the age of reason to receive Confirmation and is usually an infant.
Question #5 does address this issue. “Why do we say that Confirmation is the sacrament of adulthood? We do not say this because the sacrament must necessarily be received by adults, but because it enables us to bear witness to and defend the faith to others. This is proper to adulthood, though spiritual adulthood does not necessarily coincide with bodily age.”
The Catechism of the Catholic Church #1308 also clarifies this point. “Although Confirmation is sometimes called the ‘sacrament of Christian maturity,’ we must not confuse adult faith with the adult age of natural growth. . .”
