Michael the archangel is described in the Bible, in the books of Daniel, Jude, and Revelation, as a warrior angel who engages in spiritual combat. The word archangel means “angel of the highest rank.” Most angels in the Bible are portrayed as messengers, but Michael is described in all three books as contending, fighting, or standing against evil spirits and principalities (Daniel 10:13; 21; Jude 1:9; Revelation 12:7).
