Confirmation is a Sacrament which requires understanding of the Faith.
No, it isn’t. If you are confirmed as an older child, teenager or adult, then such an understanding should be in place, just as it should for any other sacrament. If you are confirmed as an infant, no such understanding is necessary. This is the teaching of the Church.
Before I was confirmed, I had to stand before the priest of the parish and explain the reason why I chose the saint who I chose to honor with my confirmation name.
That was a particular requirement of your parish.
It’s far more than Baptism (which is in place to cleanse one of original sin), so I can’t in my mind justify the Confirmation of infants.
Your mind is not in accord with the mind of the Church, as the Church has always confirmed infants and continues to do so. In fact, the Church teaches that an infant in danger of death should receive the Sacrament of Confirmation.
By receiving Confirmation, you are confirming that you are taking a position as a soldier for Christ; a lifetime commitment that you must make for yourself (unlike baptism when your parents and Godparents made your baptismal vows for you) and understand the importance of.
This isn’t what the Church teaches about the Sacrament of Confirmation. The Sacrament of Confirmation is a work of the Holy Spirit within you, a work of Grace that happens regardless of your knowledge or readiness.
From the Catechism of the Catholic Church:
IV. WHO CAN RECEIVE THIS SACRAMENT?
1306 Every baptized person not yet confirmed can and should receive the sacrament of Confirmation.123 Since Baptism, Confirmation, and Eucharist form a unity, it follows that "the faithful are obliged to receive this sacrament at the appropriate time,"124 for without Confirmation and Eucharist, Baptism is certainly valid and efficacious, but Christian initiation remains incomplete.
1307 For centuries, Latin custom has indicated “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.125**
1308 Although Confirmation is sometimes called the “sacrament of Christian maturity,” we must not confuse adult faith with the adult age of natural growth, nor forget that the baptismal grace is a grace of free, unmerited election and does not need “ratification” to become effective. St. Thomas reminds us of this:
Age of body does not determine age of soul. Even in childhood man can attain spiritual maturity: as the book of Wisdom says: "For old age is not honored for length of time, or measured by number of years. "Many children, through the strength of the Holy Spirit they have received, have bravely fought for Christ even to the shedding of their blood.126
Also, nowhere is it written that Confirmation is a prerequisite for Heaven, and no seven year olds have been denied Heaven because they hadn’t been confirmed yet; Baptism, on the other hand, is a prerequisite because until one is baptized, he/she has the stain of original sin.
Honestly, I think it needs to follow the first time one receives the Eucharist. You should receive Jesus’ body before you receive the Holy Spirit to guide you. Whether that means 4th grade or not until high school is a debate topic.
Having Confirmation follow the reception of the Eucharist is a historical anomaly that has only occurred in the Latin Church in the last 100 years. Do you think that the Church has figured something out in the last 100 years that it did not know for the first 1,900 years of its existence?
