According to The Book of Discipline, "Heritage Sunday shall be observed on Aldersgate Day (May 24), or the Sunday preceding that date. The day provides an opportunity for reflection on heritage, celebration of where the Church has been, how it understands itself as it shapes us today, and the meaning of Christian conferencing. Heritage Sunday calls the Church to remember the past by committing itself to the continuing call of God."
