The Feast of the Circumcision of Our Lord is a Christian celebration of
the Brit milah (ritual circumcision) of Jesus, eight days (according to
the Semitic and southern European calculation of intervals of days)[1]
after his birth, the occasion to on which the child was formally given
his name, Jesus,* a name derived from Hebrew meaning "salvation" or
"saviour".[2][3]

The circumcision of Jesus has traditionally been seen, as explained in
the popular 14th century work the Golden Legend, as the first time the
blood of Christ was shed, and thus the beginning of the process of the
redemption of man, and a demonstration that Christ was fully human, and
of his obedience to Biblical law.

The feast day appears on 1 January in the liturgical calendar of the
Eastern Orthodox Church[4] and of the Eastern Catholic Churches of
Byzantine Rite. It also appears in the pre-1960 General Roman
Calendar,[5] and is celebrated by some churches of the Anglican
Communion and virtually all Lutheran churches.
