Beware of pride when you think you are more spiritually advanced than others.
"In this time of prosperity, these beginners feel so fervent and diligent in spiritual matters and devout exercises that — although holy things in themselves humble a person — because of their own imperfection, a certain hidden branch of pride often springs up within them. From this comes a certain satisfaction with their own works and with themselves. They also develop a somewhat vain desire — and sometimes a very vain one — to speak about spiritual things in front of others, and even, at times, to teach them rather than to learn from them. In their hearts they condemn others who do not practice devotion in the way they would like, and sometimes they even say it openly. They become like the Pharisee who, while praising God, boasted about his own works and despised the publican."
