"... The true aim of our Christian life consists in the acquisition
of the Holy Spirit of God. As for fasts, and vigils, and prayer, and
almsgiving, and every good deed done for Christ's sake, they are only means
of acquiring the Holy Spirit of God. But mark, my son, only the good deed
done for Christ's sake brings us the fruits of the Holy Spirit..."
