It contrasted the idea of Original Sin in Catholic teaching to freemasonry and naturalism liberal approach:...human nature was stained by original sin, and is therefore more disposed to vice than to virtue. For a virtuous life it is absolutely necessary to restrain the disorderly movements of the soul, and to make the passions obedient to reason. In this conflict human things must very often be despised, and the greatest labors and hardships must be undergone, in order that reason may always hold its sway. But the naturalists and Freemasons, having no faith in those things which we have learned by the revelation of God, deny that our first parents sinned, and consequently think that free will is not at all weakened and inclined to evil. On the contrary, exaggerating rather the power and the excellence of nature, and placing therein alone the principle and rule of justice, they cannot even imagine that there is any need at all of a constant struggle and a perfect steadfastness to overcome the violence and rule of our passions.
