I. Faith and Reason
The Catholic Church teaches- and has always taught- that although faith is superior to reason the two can never contradict since both come to us from God, who is all truth. Some people today say you must choose either faith or reason- you can’t have both- but this notion is a fallacy which ignores 2,000 years of Catholic teaching. For Catholics, the Bible is not a science book, nor is a science book Scripture. If I want to discuss the meaning of life and my purpose in it, then I will go to a priest. If I have a broken arm and need it mended, then I will go to a doctor (same goes for seeking advice during a pandemic).

A person’s belief in God is either inherited from his family- from whom this belief is passed down- or gained through some other experience. While reason alone does not usually compel a person to believe in God, reason can demonstrate to believers and non-believers alike that belief in God is not a wish or a delusion but a rational conclusion based on reason (which, like faith, is a gift from God).
Because God is infinite, it can be difficult- though not impossible- for finite beings to describe Him using words (I prefer paintings and statues). Yet as Catholics we believe the existence of God can be known through human reason- without the aid of revelation- and God loves us and wants us to know Him. So before we even open the Bible or start talking about religion, what can human reason alone- without faith- tell us about our Creator?
Since the universe had a beginning and was created, we know someone- or something- must have existed before the universe and then created it. Christians call this someone or something God.
There is no other explanation for our universe. Something created it from nothing. In order to have created the universe from nothing, this Ultimate Cause- God- must have certain attributes. If the Ultimate Cause does not possess all of these attributes, then it is not the Ultimate Cause- and not God.

If I were going to discuss the necessary attributes of God (ie. the Ultimate Cause of the universe) then I would start with something everyone knows (or thinks they know): time. Of course, time is immaterial and exists only as an abstract concept, a tool we use to measure change. If the universe has a beginning (which it does) then this means there was a time when the universe did not exist. So, what was there before the universe? If we say nothing existed before the universe, then what started the universe? Nothing cannot start something so that answer is insufficient. However, if we say something existed before the universe and this something started the universe, then we are on solid scientific and philosophical ground since we know everything has a cause and the cause of our universe has an explanation: something else caused it.
But then we are still left with the problem of how to explain the existence of the Ultimate Cause: where did it come from and how old is it? The answer is- and must be- it did not come from anywhere and is not subject to change (time) because it has always existed and continues to exist, unchanged, outside the limitations of what we call time.
Because the Ultimate Cause of the universe is uncaused and created what we call time and space, it could not be affected by those things and would thus be timeless and immaterial. Unlike our material universe, which had a beginning and continues to change and expand, the Ultimate Cause has always existed, is changeless, and is existence itself- the very existence in which we are living at this very moment. This is what we mean when we say the Ultimate Cause- God- is eternal.
We must concentrate upon the concept of eternity; it brings us deep into the meaning of God. You and I and all men are in time: which means that we are never at any moment the whole of ourself. What we were last year, what we will be next year, all belongs to our total being; but last year has gone and next year has not arrived. There never is a moment when we are all there. We possess our being, the philosophers say, successively. Not so God. All that He is, He possesses in one single act of being. Eternity does not mean everlasting time, time open at both ends, so that however far you go back into the past there is no beginning, however you far you go forward into the future there is no end. Eternity is not time at all. It is God’s total possession of Himself.
Infinity, omnipresence, eternity- these are rich and rewarding concepts, but we should not stay with them too long a time without returning to the Gospels to meet the living God. Christ is there for us, “Whom,” as St. John says at the opening of his first Epistle, “we have seen with our eyes, whom we have looked upon, whom our hands have handled.” The Infinite we are studying is the same Infinite whom we meet in the Gospels, the same Infinite we receive in the Blessed Eucharist. 1
