TCR 435, 439, 445 - charity, merit, a moral life

TCR 435
The first thing in charity is to banish evils,
the second is to do good deeds
which may be of use to the neighbor.

[3]  People should know
that the good a person does in his body
comes from his spirit, that is, the internal man.
(The internal man is the spirit which lives on after death.)

TCR 439
In the exercise of charity
a person avoids attributing merit to deeds,
so long as he believes
that all good is from the Lord.

To attribute merit to deeds 
executed to gain salvation
is ruinous;
for evils lie hidden in this
of which the doer is quite unaware.

. . . in the sight of the angels
good done to gain merit looks like rust,
and good not done to gain merit like purple.

TCR 445
Contemplation of moral life in its essence
can show that it is life in accordance with human laws
and at the same time Divine laws.
If anyone therefore lives in accordance
with those two sets of laws treating them as one,
he is a truly moral person,
and his life is charity.
