St. Catherine of Genoa
These souls [in purgatory] cannot think,
"I am here, and justly so because of my sins,"
or "I wish I had never committed such sins
for now I would be in paradise,"
or "That person there is leaving before me,"
or "I will leave before that other one."
They cannot remember the good and evil
in their past nor that of others.
Such is their joy in God's will, in His pleasure,
that they have no concern for themselves
but dwell only on their joy in God's ordinance,
in having Him do what He will.
They see only the goodness of God,
His mercy toward men.
Should they be aware of other good or evil,
theirs would not be perfect charity.
They do not see that their suffering is due to their sins,
for that awareness would be a want of perfection,
and in purgatory souls cannot sin.
Only once do the souls understand
the reason for their purgatory:
the moment in which they leave this life.
After that moment, that knowledge disappears.
Immersed in charity, incapable of deviating from it,
they can only will or desire pure love.
There is no joy save that in paradise
to be compared to the joy of the souls in purgatory.
This joy increases day by day
because of the way in which the love of God
corresponds to that of the soul,
since the impediment to that love is worn away daily.
The impediment is the rust of sin.
As it is consumed
the soul is more and more open to God's love.
