What does CGG believe regarding the Hebrew calendar?

After an intensive study on the subject, we decided to make no substantive changes to our approach to the Hebrew calendar. The most telling conclusion we came to is that the Bible, while hinting at elements of a calendar, does not give enough information on which to formulate one. The Bible, our only reliable source, simply does not answer all the questions about the "biblical" calendar! We have thus decided to retain what was revealed to the church through Herbert Armstrong and Romans 3:2, ". . . to [the Jews] were committed the oracles of God." We have done this in part because we cannot deny that God blessed the work done through Herbert Armstrong while he was using that calendar. Thus we will follow the Hebrew calendar with its mathematical calculations and its postponements unless truly conclusive proof to the contrary becomes available.
