Nicholas Cabasilas on the ancestral sin

"...each man's soul inherited the wickedness of the first Adam. It spread from his soul to his body, and from his body to the bodies which derived from his, and from those bodies to the souls.

This, then, is the old man whom we have received as a seed of evil from our ancestors as we came into existence. We have not seen even one day pure from sin, nor have we ever breathed apart from wickedness, but, as the psalmist says, 'we have gone astray from the womb, we err from our birth.' We did not even stand still in this unhappy lot of the sin of our ancestors, nor were we content with the evils which we had inherited. So greatly have we added to the wickedness and increased the abundance of evil that the primal sin has been covered over by that which came later and the imitators have shown themselves to be worse by far than the examples."
