The 8 pointed star is a Gnostic symbol, known as the octagram of creation. It is related to Venus, and also sacred to Ishtar. In Nordic traditions the octagram is used to invoke magic and also as a protecting ideogram. Chaospheres have 8 points - order 90 degrees and chaos 45 degrees . AND This is the traditional Star of Ishtar. Composed of two intertwined squares, this is a symbol of regeneration. It is a symbol for the natural universe interweaving order and disorder, yin and yang, to create an ultimately harmonious and balanced design.

That's what the 8 point star means in religious terms. Not sure if this is helpful but hopefully will be.
