Ceremony commonly practiced in East Asia
Jesa (Korean: 제사, Korean pronunciation: [tɕe.sa]) is a ceremony commonly practiced in Korea. Jesa functions as a memorial to the ancestors of the participants.[1] Jesa are usually held on the anniversary of the ancestor's death. The majority of Catholics, Buddhists and nonbelievers practice ancestral rites, although Protestants do not.[2] The Catholic ban on ancestral rituals was lifted in 1939, when Pope Pius XII formally recognized ancestral rites as a civil practice (see Chinese Rites controversy).[2] Many Korean Christians, particularly Protestants, no longer practice this rite.[3][4] Christians generally avoid the rites,[5][6] and many emigrants avoiding the rites.[7]
Since their origins, Jesa has taken on a certain formality as human civilization has developed, which is sometimes called rituals in Confucianism.[8]
