The shield with the seven diagonal stripes is the coat of arms granted by the King of Spain to the Onaz family whose seven sons fought valiantly for the King. On the other hand, the two wolves "lobos" standing on their hind legs and fighting not over a light bulb but over a pot of food. This is the coat of arms of the family of Loyola who also had fought in many wars and were very generous in feeding their soldiers so that plenty of food would be left in the pot "the Spanish Olla" and at night, the the wolves from the surrounding countryside would come and fight over the pot of food. Thus the name lobos y olla or Loyola - a family noted for its generous care for its fighting men. Ignatius' lineage may be traced to the two families. . .Onaz and Loyola, SHS-J, a Jesuit school, traces its roots to St. Ignatius Loyola, founder of the Jesuits.

          On the foreground of the shield with the seven stripes is the head of an eagle, a truly majestic bird. It soars in the sky, is swift in flight and terrible in battle. It literally outflies, outfights, and outdistances all the other birds in the sky. Like an eagle in flight, the Sacred Heart student is supposed to soar above the rest in all aspects of human endeavor. He is not to be content with mediocrity. He should strive to do better, be true to the Ignatian ideal of MAGIS. He should strive to be more so he can do more for Christ and others. This what academic excellence and being a Man/Woman for Others is all about.
