Part of the Holy Father's mission is to remind us of our Christian heritage so the red cross on the white background responds to that. It's origins as England's flag are obscure.

In any case it is present in the Wilton Diptych which seems to commemorate Richard II's consecration of his kingdom to Our Lady - as seen above.
