A Man's Heart Is Right When He

Sacred Scripture, Since It Has No Science Above Itself, Can Dispute With One Who Denies Its Principles Only If The Opponent Admits Some At Least Of The Truths Obtained Through Divine Revelation; Thus We Can Argue With Heretics From Texts In Holy Writ, And Against Those Who Deny One Article Of Faith We Can Argue From Another. If Our Opponent Believes Nothing Of Divine Revelation, There Is No Longer Any Means Of Proving The Articles Of Faith By Reasoning, But Only Of Answering His Objections - If He Has Any - Against Faith.

The Human Mind May Perceive Truth Only Through Thinking, As Is Clear From Augustine.

Natural Inclinations Are Present In Things From God, Who Moves All Things. So It Is Impossible For The Natural Inclinations Of A Species To Be Toward Evil In Itself. But There Is In All Perfect Animals A Natural Inclination Toward Carnal Union. Therefore It Is Impossible For Carnal Union To Be Evil In Itself.

Nothing Created Has Ever Been Able To Fill The Heart Of Man. God Alone Can Fill It Infinitely.

Any Error About Creation Also Leads To An Error About God.
