Thomas Aquinas Quotes on God

“Whatever is in motion must be put in motion by another. If that by which it is put in motion be itself put in motion, then this also must needs be put in motion by another, and that by another again. But this cannot go on to infinity, because then there would be no first mover, and, consequently, no other mover; seeing that subsequent movers move only inasmuch as they are put in motion by the first mover; as the staff moves only because it is put in motion by the hand. Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.”

“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.”

“Cleanness indeed is necessary if a man’s mind is to be applied to God. For the mind of man is stained by being immersed in inferior things, as indeed all things are cheapened by admixture with things inferior to them—silver, for instance, when mixed with lead.”

“How can we live in harmony? First, we need to know we are all madly in love with the same God.”

But a dauntless faith believes”

Thomas Aquinas Quotes on Prayer

“Notice how foolish are some Christians who, when desirous of reaching certain ends attainable by nature or art, are most careful to apply such means, and would rightly regard their hopes as vain unless they applied them; and yet at the same time, they have quite false notions of the fruits to be derived from prayer: as though prayer were no cause at all, or at least but a remote one! Whence it comes to pass that, having false ideas about the causes, they fail to reap any fruit”

“By prayer, however, a man shows reverence to God inasmuch as he submits himself to Him and, by praying, acknowledges that he needs God as the Author of all his good.”

“As we said above, we ought in prayer to ask for those things which we ought to desire. But we ought to desire good things not for ourselves only but also for others, for this belongs to that charity which we ought to exercise towards our neighbor. Hence charity demands that we pray for others.”

“To know that God exists in a general and confused way is implanted in us by nature, inasmuch as God is man’s beatitude. For man naturally desires happiness, and what is naturally desired by man must be naturally known by him. This, however, is not to know absolutely that God exists; just as to know that someone is approaching is not the same as to know that Peter is approaching, even though it is Peter that is approaching….”

Prayers by Thomas Aquinas

Prayers by Thomas Aquinas

“Grant, O Lord my God, that I may never fall away in success or in failure; that I may not be prideful in prosperity nor dejected in adversity. Let me rejoice only in what unites us and sorrow only in what separates us. May I strive to please no one or fear to displease anyone except Yourself. May I see always the things that are eternal and never those that are only temporal. May I shun any joy that is without You and never seek any that is beside You. O Lord, may I delight in any work I do for You and tire of any rest that is apart from You. My God, let me direct my heart towards You, and in my failings, always repent with a purpose of amendment.”

“Give us, O Lord, a steadfast heart, which no unworthy affection may drag downwards; give us an unconquered heart, which no tribulation can wear out; give us an upright heart, which no unworthy purpose may tempt aside. Bestow upon us also, O Lord our God, understanding to know you, diligence to seek you, wisdom to find you, and a faithfulness that may finally embrace you; through Jesus Christ our Lord.”
