The key activity during the Feast of the Epiphany, celebrated in many Christian denominations, is the blessing of homes and the display of the Nativity scene. This feast, observed on January 6th, commemorates the revelation of Christ to the Gentiles, represented by the visit of the Magi. Families may also enjoy special meals, exchange gifts, and participate in church services, emphasizing themes of hospitality, faith, and reflection on divine revelation.
