In an exposition of the 6th hour Gospels (during Good Friday) St. Dionysius the Areopagite says that "through the Divine Providence of God, that he covered Himself in humanity, thus shielding His Divinity from the devil till he released Adam from his lordship and inherited Eternal Life"
St. Dionysius then goes on to explain, "that when she [St Mary] had fallen pregnant, Satan assumed it was due to Joseph and overlooked the saying of Isaiah, "behold, the virgin shall conceive & bear a Son and you shall call His name Immanuel" (Isaiah 7:14)"
I always thought satan was mindful of Christ's Divinity. ALL these prophecies are a clear give away. So was Satan aware that Jesus was the Son of God?
