I believe in the Lunar Sabbath, or in other words the Sabbath day being determined by the phase of the moon. At some point I want to write an artile about it myself when I have time.

Here are some things I have writen regarding the Sabbath:

Highlights from Sunrise or Sunset
On The Morrow / Morning

Val was were I first head of this idea. I was 50/50 after reading his Serious about the Sabbath (backup) article.

I then came across this video series which is what convinced me:
Lunar Sabbath Proof 1/3
Lunar Sabbath Proof 2/3
Lunar Sabbath Proof 2 part C/3
Lunar Sabbath Proof 3/3 (focus is on historical evidance)

I then came across things like this in history videos. For example how the Egyptians used the moon for their month. (I’d share the video with you but it has been removed from YouTube.)

At some point I came across these videos.

The website Creation Calendar is full of articles showing the Lunar Sabbath from the scriptures. It also has rebuttals on arguments aganist the Lunar Sabbath.

Many know about Nehemia Gordon. He made a comment about atleast once that I have run across.

Jews adapted stop following the lunar calendar because of the Romans thinking they would go back to it when the Savior comes

Here are some pretty good quotes from Jewish sources.

The New Moon is still, and the Sabbath originally was, dependent upon the lunar cycle. Both date back to the nomadic period of Israel. Originally the New Moon was celebrated in the same way as the Sabbath; gradually it became less important while the Sabbath became more a day of religion and humanity, of religious meditation and instruction, of peace and delight of the soul. – The Universal Jewish Encyclopedia, page 410

In the time of the earliest prophets, the New Moon stood in the same line with another lunar observance, the Sabbath. – Scribner’s Dictionary of the Bible, 1898 edition, page 521

One thing to think about all the holidays in Lev 23 are based on the moon, and I personally would include the Sabbath in with that.

Another subject that needs to be addressed are mistranslation regarding the Sabbath.

Acts 20:7 Says What?

The new moon is the conjunction of the moon not the full moon.

Is Full Moon New Moon ???
