In this book Guimarães offers two reasons:
First, Vatican Council II introduced a new morals in the Catholic Church. This new morality is meant to adapt itself to modern psychological theories that presume sexual desires should not be repressed.
Second, homosexuality and pedophilia infiltrated such high positions in the Catholic Hierarchy that for the present-day Vatican to punish the guilty parties would be tantamount to gravely damaging itself.
These are causes many Catholic suspect, but only few have the courage to express. This book constitutes a noble denunciation made for the love of the Catholic Church, and turned toward Our Lord asking Him to heal her.
The work is also a valuable resource tool, presenting Catholic teaching on homosexuality with quotes from Scriptures, Popes, Saints and Canon Law.
