Postponements PROVE Lunar Sabbaths

What are postponements? They are Jewish regulations to the Hebrew calendar that were implemented in the 4th century. Something occurred around that time to cause the Jews the need to change, or postpone, the annual holy days. The weekly Sabbath all of a sudden began to come into conflict with commanded work days, new moons, and annual Sabbaths. This was a cause of inconvenience and so they made up these rules to postpone certain days, and thus causing these days to be observed on days not authorized by God. These postponements are purely man's invention and tradition. But why were these postponements never needed for the previous millenniums? The simple reason is because the calendar was changed in the 4th century which made the week divorced from the appearance of the moon. The Hebrews adopted the newly instituted continuous cycle of weeks of the Romans during the time of 
Constantine  So instead of the Sabbath being reckoned by the moon, it was observed every 7th day with a continuous cycle of weeks. This caused conflict between the weekly Sabbath and the rest of God's calendar, therefore postponements were implemented. The scriptures never speak of postponements, they were not observed or needed in the Messiah's day, and they are not authorized by God. The Jews were entrusted with the preservation of the oracles of God, or the scriptures. But they are not authorized to add to or subtract from these oracles that they have been entrusted with. 

Postponements prove the lunar Sabbath because postponements are not needed in God's luni-solar calendar. Postponements on the other hand are needed if you observe the Sabbath according to the continuous weekly cycle. Because postponements are not authorized by God, are man's invention, and are purely traditions of man, the Sabbath associated with it is proven false. The Saturday Sabbath and the postponements go hand and hand. The lunar Sabbath is proven true because it is the only way to observe God's annual holy days and his Sabbath without the conflicts in schedule.
