Christians from this church should NOT eat chicken from today as respect to the chickens.
In AD66, the Judea tribes did rid of the Roman empire but only lasted 3 years. This was known as the Jewish Revolution in history and the champ was Simon Dekobar/Decobar.
Then it lost to the Roman and the angry AMDK Roman took revenged and place a giant statue of a PIG in the Jewish holy temple to screwed them.
Therefore then onwards, Jewish refrain from eating the animal Pig. Pig has same status as Yahweh in Jewish history, don't play play well respected.
and the 666 beast in the Revelation chapter refers to this period AD66, and the other 6 means this happened during the 6th emperor of Roman, emperor Vespasian.
