In Illo Tempore: 16th Sunday after Pentecost

Fr. John Zuhlsdorf explains that pride caused the fall of Satan, the apostate angels, and the human race through the first parents. Writing for OnePeterFive, Zuhlsdorf notes that pride transformed angels into devils and changed paradise into a world of suffering.

Citing St. Bernard of Clairvaux, Zuhlsdorf describes pride as the beginning of every sin. He states that pride ruins virtues by attempting to claim God's gifts as one's own.
