Vasco and his humanist priest had their Catholic theology all wrong, and their heresy had disastrous consequences. There is a tendency within Catholic circles to view oneself only as an irredeemable sinner. This fills one with shame and causes a sort of false humility that convinces oneself to reject all good things ("his professional success was at odds with how he thought of himself; he felt he didn’t deserve it"). One further effect of focusing excessively on one's sinfulness, rather than on the love of God, is that quitting sin is much harder. The priest's belief that man is inherently good is also heresy at odds with scripture.

The truth as the Church would describe it is that man is intrinsically sinful but has been redeemed through Christ, and that should fill one's heart with joy and gratitude. No, man does not deserve any good thing, but when good things happen they should be appreciated as gifts, not rejected out of shame. This is true humility.

Some claim that self esteem should instead be replaced with self-compassion. This is a good idea that is in line with Church teaching, since to see yourself as God sees you (with unconditional love in spite of one's faults) is to adopt a perception which is based in truth, rather than the self-esteem movement which is based on convincing yourself of the lie that you are unconditionally good.
