My apologies in advance for the title as I couldn't think of a good one to address my question. As some of you know, along with the word of God I also study demonology and have been for the past 2 years. Some books (mostly written by Catholics) insist that we pray to God and His angels for protection. However, from what I understand, the angels are ministering spirits who do God's bidding (Hebrews 1:14; Psalms 103:20). When demons and devils present themselves, are we to call upon God and his angels (such as St. Michael the archangel and say his prayer), or do we just pray/call upon God?
