The magi’s coming to Jerusalem in order to pay homage to the king of the Jews shows that they seek in Israel, in the messianic light of the STAR OF DAVID, the one who will be king of the nations.
One need not be a believer in Judaism to understand how this symbol provides one of most simple, yet comprehensible, ikons used to represent such concepts as Heaven and Earth, God and Man, Soul and Body, Material and Spiritual, Mountain and Valley, etc. Throughout the Middle Ages, many a Christian Gentile, especially the more learned among them, understand this symbol as, not only representing a unity of opposites, such as the elements of Earth and Air, or Water and Fire, but also as an expression of complementary concepts, much like the ebony and ivory keys to a piano which, when played correctly and by using the correct combinations, was capable of creating something beautiful- like the Latin Mass at its finest and most profound.
Their coming means that pagans can discover Jesus and worship him as Son of God and Savior of the world only by turning towards the Jews and receiving from them the messianic promise as contained in the Old Testament
Historically speaking, the Catholic Church wasn’t very prone to call the hexagram the Star of David (or Magen David in Hebrew). In fact, for several centuries before the modern term ‘Star of David’ ever became part of everyday vocabulary, and long before this symbol ever became specifically Jewish, the Church preferred to refer to the hexagram as the Star of Creation, or the Creator’s Star. Now the obvious question that might come to readers’ minds is why on earth did the Christian authorities ever refer to this symbol in such a manner. The Star of Creation? Whatever does that mean?
Obviously, there must be a reason behind this particular designation and the following analysis of the Creation story in the 1st Chapter of Genesis (Genesis 1:1-27) is a humble attempt to explain the reasons why-
The six-pointed star is the 
Creator’s Star or Star of Creation. Its six points stand for the six days of creation.
The easy answer is to simply point out that God’s Creation includes both the Heavens and the Earth, Mountains and Valleys, Clouds and Seas, Volcanoes and Tornadoes, so the symbolic representation of BOTH distinctly different items placed together would of course signify the reality that Creation is filled with a diverse array of BOTH phenomenon- not to mention the fact that every snowflake is basically a Star of David, in one form or another.
All of this is true of course, but it doesn’t really truly answer the question completely. Why not call it the God’s Star, rather than the Creator’s Star?
– The Heavens= Up Triangle –> ‘God created the Heavens’ – The Earth= Down Triangle –> ‘God created…the Earth.’ = God’s Creation= David –> ‘God created the Heavens AND the Earth.’
(2) The earth was formless and void, and darkness was OVER the surface of the deep, and the Spirit of God was moving OVER the surface of the waters.
– Darkness= Up Triangle – The Deep= Down Triangle = Darkness OVER the Deep= Star of David –> ‘darkness was OVER the surface of the deep’
– Spirit of God= Up Triangle – The Waters= Down Triangle = Spirit of God OVER the Waters= Star of David –> ‘the Spirit of God was moving OVER the surface of the waters.’ _________________________
(4) God saw that the light was good, and God SEPARATED the light from the darkness. (5) God called the light day, and the darkness He called night.
