St. Thomas Aquinas and the 5 ways to prove God's existence
from
Summa Theologica

Aquinas's 5 Proofs for God's existence
Here is a brief video that will explain the philosophy and theology of Aquinas.
1. Argument from Motion

1. Our senses prove that some things are in motion.

2.Things move when potential motion becomes actual motion.

3.Only an actual motion can convert a potential motion into an actual motion.

4.Nothing can be at once in both actuality and potentiality in the same respect (i.e., if both actual and potential, it is actual in one respect and potential in another).

5.Therefore nothing can move itself.

6.Therefore each thing in motion is moved by something else.

7.The sequence of motion cannot extend ad infinitum.

8.Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.

2. Argument from efficient causes

1. We perceive a series of efficient causes of things in the world.

2.Nothing exists prior to itself.

3.Therefore nothing is the efficient cause of itself.

4.If a previous efficient cause does not exist, neither does the thing that results.

5.Therefore if the first thing in a series does not exist, nothing in the series exists.

6.The series of efficient causes cannot extend ad infinitum into the past, for then there would be no things existing now.

7.Therefore it is necessary to admit a first efficient cause, to which
everyone gives the name of God.


3. Argument from possibility and necessity

1. We find in nature things that are possible to be and not to be, that come into being and go out of being i.e., contingent beings.

2.Assume that every being is a contingent being.

3.For each contingent being, there is a time it does not exist.

4.Therefore it is impossible for these always to exist.

5.Therefore there could have been a time when no things existed.

6.Therefore at that time there would have been nothing to bring the currently existing contingent beings into existence.

7.Therefore, nothing would be in existence now.

8.We have reached an absurd result from assuming that every being is a contingent being.

9.Therefore not every being is a contingent being.

10.Therefore some being exists of its own necessity, and does not receive its existence from another being, but rather causes them.
This all men speak of as God.


4. Argument from the Gradation of Being

1. There is a gradation to be found in things: some are better or worse than others.

2.Predications of degree require reference to the “uttermost” case (e.g., a thing is said to be hotter according as it more nearly resembles that which is hottest).

3.The maximum in any genus is the cause of all in that genus.

4.Therefore there must also be something which is to all beings the cause of their being, goodness, and every other perfection; and this we call God.


5. Argument from Design
1. We see that natural bodies work toward some goal, and do not do so by chance.

2. Most natural things lack knowledge

3. But as an arrow reaches his target because it is directed by an archer, what lacks intelligence achieves goals by being directed by some intelligence.

4. Therefore some intelligent being exists whom by whom all natural things are directed to their end; and this being we call God.

Ideas to Consider
Theology:
The study of the nature of God and religious truth; rational inquiry into religious questions.

Philosophy:
The study of the nature, causes, or principles of reality, knowledge, or values, based on logical reasoning.

Can the two effectively be combined?
