BAPTISMAL NAME
The name that a person receives at Baptism. According to the Church's tradition, the baptismal name "should be taken from some person whose eminent sanctity has given him a place in the catalogue of the saints. The similarity of name will stimulate each one to imitate the virtues and holiness of the Saint and, moreover, to hope and pray that the one who is the model for one's imitation will also be his advocate and watch over the safety of his body and soul" (Catechism of the Council of Trent, Baptism).
CONFIRMATION NAME
The additional name that a person assumes when receiving the Sacrament of Confirmation. While not strictly required, it is recommended as a sign that the one confirmed has entered on a new way of life, having received a new sacramental character as a witness of Christ. As in the Baptismal name, the name of a saint is chosen to be the model for one's imitation.
