• The truth of our faith becomes a matter of ridicule among the infidels if any Catholic, not gifted with the necessary scientific learning, presents as dogma what scientific scrutiny shows to be false.
• Hold firmly that our faith is identical with that of the ancients. Deny this, and you dissolve the unity of the Church.
• There is nothing on this earth more to be prized than true friendship.

• Moral science is better occupied when treating of friendship than of justice.
