For this body is a similitude of the soul,
and the soul is the image of the Spirit ;
and as the body without the soul is dead,
and unable to do anything at all,
so without the heavenly soul,
that is, without the Divine Spirit,
the soul is dead from the kingdom,
being unable to do any of the things of God without the Spirit.
Sacraments they held to be useless, though harmless, the only spiritual
power being prayer, by which one drove out the evil spirit which baptism
had not expelled, received the indwelling of the Holy Ghost, and arrived
at union with God, becoming so perfect that the passions ceased to trouble.
