Thomas Aquinas's Five Arguments For The Existence Of God

St. Thomas Aquinas wrote five arguments for the existence of God, part of his Summa Theologiae. Thomas’ second argument for the existence of God is one of the most compelling, as we can see examples from both the Bible and nature to support it. In the cause and effect argument, Thomas starts off with providing reason that all things that exist in the world must have an original cause to all the effects we see on earth. Thomas states, “There is no case known in which a thing is found to be the efficient cause of itself” (Summa Theologiae I 2:3).Thomas is proving that nothing in nature exists without having a cause, and therefore it is impossible for something to exist in nature without something, the effect, prior to it causing it to exist. The bird, the effect, that flies around your backyard was created by two prior birds, the cause, before that one, and you can keep tracing the cause of each bird back far enough when

If you use something in the universe, such as a star, you can attempt to follow the causes of each effect. The star is an effect of a high concentration of interstellar gas and dust in an extremely cold region of space. The next question is, where does interstellar gas and dust come from? Interstellar gas is formed from molecular gas, which was formed by a theorized concept, called the ‘big bang theory’. The big bang was an enormous blast of energy throughout the universe, which formed all things instead the universe. Using Thomas’ logic of causes and effects in world, this massive explosion could have produced the first effects in the world since science does not have a theory to what caused the big bang, Thomas would state, whatever the cause of the big bang is an uncaused cause. This would be considered God, which God’s only effect could be the big bang theory in which that would create other effects and eventually over time into the world we
