The constant faith of the Church attests to the faith in the
permanency of human death. That faith is best described in
the writings of the Fathers of the Church.
Irenaeus of Lyons
(circa 130-200), set forth the
idea of death as the separation of the soul from the body.
The identical idea is found in
in the third century;
Gregory of Nyssa
(circa 330-395) in the fourth.
