Frequently on their first Holy Communion, boys will dress in their finest suits, and girls will often wear special white First Communion dresses and veils (their dresses should fit the rules of feminine modesty in Church – nothing sleeveless, etc.). Some parishes will say it is a reminder of putting on Christ, as the white garment offered at their baptism. On a mundane, sociological level, a child’s “First Communion” is a rite of passage, an acknowledgement that he has reached the age of reason and is now liable for many of the penalties involved in ecclesiastical censure; it is, in other words, a marker that the child is growing up… Gifts are given to the new communicant (typically Rosaries, prayer books, Bibles, etc.), and a party typically follows the Mass during which he first receives the Sacrament. These mundane aspects of a child’s “First Communion” should never, *ever *overshadow the greater reality! In some parts of the world, a child’s First Communion is turning into a lavish, extravagant, keeping-up-with-the-Joneses bat-mitzvah, with little girls, wearing dresses that cost hundreds and hundreds of dollars, carried about by limousine to parties with expensive ice sculptures and *la-di-da *waiters. It is uncanny to me.
While a child’s First Communion should be memorable and very beautiful, it should, above all, be holy and with all priorities in place. On the more fundamental and profound level, First Communion is an initiation into one of the Great Mysteries. Parents should prepare the child by firmly grounding him in basic catechesis. While it’s the priest’s decision as to whether or not your child is adequately prepared, it is your job as a parent or godparent to do the preparing; it is the parents and godparents who are ultimately responsible for the Catholic education of the child. The child should understand what transubstantiation is. He should know that God, Who created all things – the Sun and Moon and Stars – is able to speak things into reality, and that at the Mass, this is what God, through His priest does. The child should understand that though the accidents of bread and wine remain, what the bread and wine truly become is Sacrament. They will learn all of this best by watching the adults around them, especially parents and godparents.
