Every judgement of conscience, be it right or wrong, be it about things evil in themselves or morally indifferent, is obligatory, in such wise that he who acts against his conscience always sins. Thomas Aquinas
It is necessary to posit something which is necessary of itself, and has no cause of its necessity outside of itself but is the cause of necessity in other things. And all people call this thing God. Thomas Aquinas
Law is nothing other than a certain ordinance of reason for the common good, promulgated by the person who has the care of the community. Thomas Aquinas
Love must precede hatred, and nothing is hated save through being contrary to a suitable thing which is loved. And hence it is that every hatred is caused by love. Thomas Aquinas
The knowledge of God is the cause of things. For the knowledge of God is to all creatures what the knowledge of the artificer is to things made by his art. Thomas Aquinas
