A comparison between a christian and a Jewish coming of age ceremony?

Jewish Coming-of-Age Ceremonies for their children are called Bar or Bat Mitzvahs(depending upon the sex of the child receiving the ceremony). For the boy, he receives his Bar Mitzvah at age 13 years. For the girl, she receives her Bat Mitzvah usually at 12 years(occasionally 13 too).

Bar & Bat Mitzvah Ceremonies are celebrated on the Sabbath Day closest to the birthday of the child receiving the Ceremony.

The Sacrament of Confirmation is the Christian Coming-of-Age Ceremony. It is for both boys & girls, & they usually receive this Sacrament approximately between the ages of 12 - 15 years.

While Jewish children receive Bar/Bat Mitzvahs individually, Christian children receive the Sacrament of Confirmation in a group. In the Catholic Church, a young Confirmation candidate may choose a Patron Saint for him/herself.
