Venial sin, it is true, does not make our Communion unworthy, but it is the reason why we
profit so little from it.

See, for instance, how many Communions you have made. Are you any better? No, perhaps.
Why? Because you retain nearly always the same imperfections. You have a horror of big sins which
would kill your soul, but for all these acts of impatience, these murmurings when some trouble or
some annoyance or contradiction befalls you, for these little evasions in speech.
You wish everyone should love you, and have a good opinion of you. You do not make the
least effort to correct yourself.

Set to work to destroy in yourself all that is not pleasing to Jesus Christ, to speak willingly to
those who have caused you pain, to be pleased to see them, to love them sincerely, to practise the
perfect renouncement of yourselves and you will see how your Communion will carry you forward
with great strides towards Heaven. The more you do it, the more you will feel yourself detached
from sin and carried to God.
