In the Creed we profess that we believe in God the Father, Almighty, maker of heaven and earth, of all that is visible and invisible. Well, what is the invisible? It is the spiritual creatures God has made, the Angels, one third of which rejected God, but that is for another time. These fallen angels became Satan and the demons. They were originally good angels who refused to love and serve God and share in His life. Angles and demons are a whole civilization of persons, pure spirits without bodies, who day in and day out which we ignore. It is a civilization that is far more intelligent, powerful and numerous than the human civilization. One key mission the angels have is to help us make it safely home, while Satan and demons do all in their power to destroy our souls in hell.
We must start tapping into the supernatural power of our Guardian Angels. We are in a spiritual war. We pray to St. Michael, “Defend us in battle…” if you don’t see the battle, that’s the problem. We are in a spiritual battle between good and evil, a battle between God’s greatest creature, Mary and the most heinous creature, Satan. We need to recognize the reality of Angels and demons and develop a powerful collaboration and friendship with our Guardian Angel.
CCC 330 As purely spiritual creatures, angels have intelligence and will: they are personal and immortal creatures, surpassing in perfection all visible creatures, as the splendor of their glory bears witness.
God is the first cause of all things and He works through secondary causes. The first of these secondary causes are the angels. There are nine groupings or Nine Choirs of Angels according to Scripture and Tradition. Colossians 1:15-16 Christ is the image of the unseen God and the first-born of all creation, for in him were created all things in heaven and on earth: everything visible and everything invisible, Thrones, Dominations, Sovereignties, Powers - all things were created through him and for him.
1st Order of Angels is focused on adoration and contemplation of God – they are the Seraphim, Cherubim, and Thrones
2nd Order of Angels assigned to the Government of the Cosmos – the operation of all material things: planetary bodies and the courses of nature – the Dominions; the Powers, whose role it is to give us aid against Satan; and the Virtues – strengths against temptations. In Latin, virtus means strength.
3rd Order – Principalities, responsible for human government; Archangels, whose special task is to direct humanity; and the Guardian Angels
CCC 336 From its beginning until death, human life is surrounded by their watchful care and intercession. "Beside each believer stands an angel as protector and shepherd leading him to life." Already here on earth the Christian life shares by faith in the blessed company of angels and men united in God.
God has created and given you a Guardian Angel whose principal mission is to help get you to heaven. This spiritual person knows you far better than you know yourself – they have a supernatural knowledge of you, your strengths, weakness and all you have ever done. God wants us to tap into the help of our Guardian Angel. We don’t have to fight this spiritual battle alone. By the way, your Angel is far more intelligent and powerful than you are. The Angelic intellect is immediate. Your Angel does not need time to think things over. He knows exactly what you should do – so why not develop a close collaboration with him. We can do this by developing a friendship with them. Pray to your angel, talk to him regularly, pay attention to his guidance and follow his inspirations.
