What the Bible says about Day of Atonement as a Spiritual Feast
(From Forerunner Commentary)

Leviticus 23:26-32 To put it even more succinctly, on the Day of Atonement, we are not to eat, drink, or work at all for the entire twenty-four-hour period. It is a day of worship, instruction, prayer, and humbling ourselves before God in thanks for His marvelous work in atoning for all sin and in bringing mankind into unity with Him (see Leviticus 16:29-34; Isaiah 58:1-12; Revelation 20:1-3).

Acts 27:9 Luke, writing this over 30 years after Christ's death, makes it very clear that the early church observed this holy day. Richard T.
