St. Moses on Soul-sleep

St. Moses the Ethiopian ca. 330-405

At least we must avoid, and shun with the utmost horror, that wicked punctuation of the heretics, who, as they do not believe that Christ could be found in Paradise on the same day on which He descended into hell, thus punctuate Verily, I say unto you today, and making a stop apply you shall be with Me in Paradise, in such a way that they imagine that this promise was not fulfilled at once after he departed from this life, but that it will be fulfilled after the resurrection, as they do not understand what before the time of His resurrection He declared to the Jews, who fancied that He was hampered by human difficulties and weakness of the flesh as they were: No man has ascended into heaven, but He Who came down from heaven, even the Son of Man Who is in heaven: Jn. 3:13 by which He clearly shows that the souls of the departed are not only not deprived of their reason, but that they are not even without such feelings as hope and sorrow, joy and fear, and that they already are beginning to taste beforehand something of what is reserved for them at the last judgment, and that they are not as some unbelievers hold resolved into nothing after their departure from this life: but that they live a more real life, and are still more earnest in waiting on the praises of God. (St. John Cassian, Conference 1.14)
