Last week, someone close to me expressed that they felt uncomfortable keeping the Moedim (Feast of Yahvey outlined in Leviticus 23) as I do, because they felt like we were imitating the Jewish people and stealing their traditions. Nothing could be further from the truth. Until the Roman Emperor Constintine forbid them to do so well into the fourth century A.D., the church kept the seventh day Shabbat (Sabbath) and all of the Moedim. These are not Feasts of the Jews, they are the Feasts of Yahveh -- the God of Jews and Christians. In Leviticus 23, Yahveh commands His people that His Moedim are to be kept as perpetual statutes throughout their generations where ever they live. No where in Scripture does He indicate that this responsibility would end when Messiah comes, or because a pagan Roman Emperor decided it was no longer appropriate to do anything the detestable Jews did (Constantine's words, not mine).
Contrary to the supercessionist (replacement theology) antinomian (anti-Torah) doctrine of most of the church, Colosians 2: 8-19 does not command gentile Christians to ignore Yahveh's instructions in Leviticus 23 nor does it annul the Fourth Commandment, to remember the Sabbath day and keep it holy. In that passage Paul is warning gentile Christians about those who would, through philosophy and vain deception, try to take them captive to the "traditions of men" and "principles of the world". It is those people that Paul says should not be allowed to judge gentile Christians regarding food or drink, festivals, new moons or Sabbaths. Paul instructs that they should instead be judged by the body of Messiah, which I might add kept the seventh day Sabbath and all of the Moedim faithfully for another 270 years. In fact Scripture indicates that we will celebrate the feasts with Messiah in His millennial kingdom.
That brings me to Yom Kippur and how believers in Messiah Y'shua can keep this feast in a manner consistent with both our Hebrew roots and our belief in Y'shua's atoning sacrifice. Although we no longer need the blood of goats and bulls to cover our sin because Y'shua's sacrifice accomplished that once and for all; it certainly does not hurt believers in Messiah Y'shua to take stock of their relationship with Yahveh during the Ten Days of Awe and repent of anything that has come between us. There is also no better time to pray for the "Apple of Yahweh's Eye", His Jewish People, that as they seek their God during this High Holiday season, they may find the Jewish Messiah, Y'shua. So I recommend that believers in Messiah Y'shua fast and pray with the Jewish People on Yom Kippur in the hope that they will meet Him this year.
