42-44 And the Spirit has in a similar manner its own appropriate distinct body, the spiritual species can by no possibility overrun into and mix with a distinct species of earthly things. Hence the contrast so difficult to grasp in the resurrection of the dead, whereby the spiritual species with its appropriate body appears in substitution of the former human expression of life. On the one hand weakness, corruption, dishonour, comparable to the body of a seed which rots and dissolves beneath the layer of soil; and on the other hand power, glory and incorruption, of which the green shapely stalk of corn may be taken as a simile. But the absolute distinctness of species on earth is a lesson to us, whereby the mind grasps the significance of the great spiritual category of things wholly distinct from the earthy. These things possess spiritual bodies and have no connection with earthy bodies. Their glory is distinct.
