When Yahuah created three types of days.
Three types. New Moon days. Work days. Shabbath days.
Eze 46:1 THUS says ADONAI YAHUAH; The gate of the inner court that looks toward the east shall be shut the six working days; but on the Shabbath it shall be opened, and in the day of the New Moon it shall be opened.
New Moon is not Shabbath.
And he said, Wherefore will you go to him today? it is neither New Moon, nor Shabbath. And she said, It shall be well
And it shall come to pass, that from New Moon to his New Moon, and from Shabbath to his Shabbath, shall all flesh come to worship before me, says YAHUAH.
Saying, When will the New Moon be gone, that we may sell grain? and the Shabbath, that we may set forth wheat, making the ephah small, and the sheqel great, and falsifying the balances by deceit?
Let no man therefore judge you in meat, or in drink, or in respect of a feast day, or of the New Moon, or of the Shabbath:
You claim to be Israel,
yet you choose to ignore Yahuah’s New Moon!
Who changed it?
Who told you to follow the Gregorian calendar?
Who authorized it?
