St. Macarius on the Soul After Death

St. Macarius the Great ca. 300-391
 
When the soul of a man departs from the body, a certain great mystery is there enacted. If a person is under the guilt of sin, bands of demons and fallen angels approach along with the powers of darkness which capture the soul and drag it as a captive to their place. No one should be suprised by this fact. For if, while a man lived in this life, he was subject to them and was their obedient slave, how much more, when he leaves this world, is he captured and controlled by them? (The Fifty Spiritual Homilies, Homily 22) 
 
Like the tax collectors who sit along the narrow streets and snatch at passers-by and extort from them, so also the demons watch carefully and grab hold of souls. And when they pass out of the body, if they are not completely purified, they are not permitted to go up into the mansions of Heaven there to meet their Master. For they are driven down by the demons of the air. But if, while they still live in the flesh, they shall, because of their hard toil and much struggle, obtain from the Lord on high grace, they, along with those who through virtuous living are at rest, shall go to the Lord, as He promised. “Where I am, there also shall My servant be.” (Jn. 12:26) (ibid., Homily 43)
