Levitical priests throughout the temple years, kept the feast days. They didn't all do their temple work at the same time, they were divided into 24 "courses" in which each "course" had their allotted time or turn, to do service.
Levites are members of the tribe of Levi, the third son of the patriarch Jacob. Members of the tribe are either priests (Kohanim) or Levites, their status being established by family tradition and which family they were born into. Only members of the tribe of Levi who were descendants of Aaron could be priests.
The offering of the sacrifices was the function of the priests. The function of the Levites was to assist in various ways and also to provide the music, be security guards, and gatekeepers.
Yes, they are real people -- and there are still Levites (descendants of Levi) today. Levites still act as spiritual leaders among the Jews and Jewish proselytes to this day.
They (and many Christians) feel the true fulfillment of a son of the tribe of Levi is to once again serve God in the Holy Temple in Jerusalem.
Since 1987 the
Temple Institute has been dedicated to the reconstruction of the Temple in Jerusalem. They are preparing for this by getting things ready, like the manufacture of various pieces of Temple furniture and vessels; some of the High Priest’s vestments etc. Their goal is to have a fully functional Temple, once again, in Jerusalem. It is claimed that every aspect of this work is carefully based on Scripture and Jewish writings.
There's the excitement over a finding perfect "red heifer". The ashes of perfect red heifer are needed (according to the ancient jewish rituals) to "purify" today's Levitical priesthood and to "purify" the temple mount in preparation for the building of the Third Temple.
The claim is made that according to Malachi 3:1-2 the Messiah will come to this rebuilt Temple. The Levitical priests will be serving in the restored temple, over there in Jerusalem, throughout the coming millennium.
Of course this includes the revival of all the Jewish feasts as well. Something that is being promoted not only in Jewish communities but in many Christian circles today. Though right now they are more "memorial of the feasts", once the plan for a restored temple is reality, they will be fully executed feasts complete with sacrifice.
Also, circumcision was and still is an important marker of Jewish identity. Will Gentiles be required to be circumcised in order to enter the rebuilt temple, (if it is rebuilt)?
The above is the action plan that you will find all over the internet and Christian Radio stations.
BUT IT IS NOT ADVENTIST BELIEF.
Adventists believe in a heavenly sanctuary,
a heavenly High priest -- Jesus Christ
a heavenly millennium.
The earthly was merely a shadow
the reality is the heavenly.
