Answer: When exactly God created angels is open for debate, but what is known for sure is that God created everything good because God, in His holiness, cannot create something sinful. So when Satan, who was once the angel Lucifer, rebelled against God and fell from heaven (Isaiah 14; Ezekiel 28), one third of the angelic host joined his insurrection (Revelation 12:3-4,9).
Ang Diyos, sa Kanyang kabanalan ay hindi lilikha ng anumang bagay na makasalanan. Kaya nang si Satanas, na noon ay ang anghel na si Lucifer, ay nagrebelde laban sa Diyos at pinatalsik sa langit (Isaias 14; Ezekiel 28), ang ikatlong porsyento ng bilang ng mga anghel ay nakilahok sa Kanyang paglaban sa Diyos (Pahayag 12:3-4,9).
