We uploaded a video lesson on our Youtube page here explaining why our Igbo ancestors did not keep the Sabbath in Africa.
We started by explaining the origins of the Sabbath.
The 7-day Sabbath, and every other Hebrew feast was instituted by man to the liking of the Most High.
And since the Most High liked them, they remained ordained in the heavenly tablets.
The Sabbath was instituted by Moses to give the Hebrew slaves in Egypt one day of rest.
In the video, we explained that the children of Gad who were the first to come to Africa from the Middle East came before Moses was born.
As a result they did not know about the 7 day Sabbath.
And subsequent Hebrews that came to join them had already forgotten the Sabbaths and other ordinances.
As a result, they had to learn from the children of Gad who were already on ground.
This is explained in the attached slide.
