What is an Imaculate Conceptionwhy do you celebrate it?

This question often catches a lot of people out. Jesus was born because of the VIRGIN BIRTH, God placed him in Mary's womb.

Immaculate Conception is what happened to MARY.

It means that from the moment Mary was concieved she was granted immunity from all suspicion of sin.

The Virgin Birth is mentioned in Luke and Matthews Gospels but not in Mark or Pauls. Infact Paul clearly states that "Jesus was made of the seed of David, according to the flesh."
