God's Appointed Times
We do not consider these "Jewish Feast Days" for they are True Biblical Feast Days. In following our Lord and Savior, who is Truth, we follow the Lunar Calendar for His Commandments pertaining to God's Appointed Times. The True Sabbath observance is from sundown on Day 6 to sundown Day 7, and then on the next 3 to 4 sabbaths following the new moon, according to Genesis 1:14. Rosh Chodesh observance is the first day of every biblical month. The Feast Days, or Appointed Times, are Pesach (Passover), Shavuot (Pentecost), Rosh Hashanah (Feast of Trumpets), Yom Kippur (Day of Atonement), Sukkot ( Feast of Tabernacles), *Chanukah (Festival of Lights), and *Purim (Feast of Esther).
In Leviticus 23, God calls the feasts “my appointed times”. The feasts are God’s way to remind His people that He is Lord of the calendar, King of creation, Ruler over time, past, present, and future. He established special times to meet with us in a particular way to commemorate events in His dealings with man. When we celebrate the feasts in the way He ordained we reinforce the relationship He established with us and honor His sovereignty over us.
The timing of the feasts is important...God is very specific on when we are to celebrate these events. The calendar used to calculate the dates, the Jewish calendar, is based on the lunar cycle. (verses the solar cycle used in the Gregorian, or “modern” calendar) Psalm 104:19 says “He made the moon for the seasons; the sun knows the place of its setting.” Since the calendar is based on the cycle of the moon. The arrival of the new moon is a crucial event. In ancient times three witnesses were needed to confirm when the first sliver of the moon was visible. At that time a fire was lit on the Mount of Olives to signal other watchers to light fires on the surrounding hills until the message was spread throughout Israel that a new month had begun. Month and moon are the same word in Hebrew: “chodesh”. Thus a new month is called “Rosh Chodesh”, head of the month.
