How to Answer Those Who Doubt or Deny God’s Existence

By February 26, 2016 Apologetics 4 Comments

“God? You believe in God? Hasn’t science demonstrated that there is no God — or at least no evidence for God? Haven’t we learned that everything we see about us and within us can be explained without the need of a Creator?”


Catholics believe that while God can be known through his created works (Romans 1:20), including we who have been specifically made to be mirrors of his image and likeness (Genesis 1:26,27), he has revealed himself most fully in his Son, our Lord Jesus Christ, who is “the image of God’s glory and the exact representation of his being” (Hebrews 1:3). To understand God, therefore — who God is and what his intentions are — we need to look primarily to Scripture and the teaching of the Church.

At a same time, it’s important that we learn how to defend our belief in God in ways that will be meaningful to those who don’t share our faith in Scripture or the Church — especially as our society becomes more secular and each of us has members of our family, friends, co-workers, neighbors who doubt or outright deny the existence of God.

Catholics need not sink into silence in the face of atheist claims. This is something we can all learn to do. And we need to! As St Peter wrote to the earliest believers: “Set apart Christ as Lord in your hearts and always be ready to give an answer to anyone who asks you to give a reason for the hope that is in you, but do it with gentleness and reverence” (I Peter 3:15).

If you need support in this area, I encourage you to start by looking at the God page of the Calling All Converts site. It’s right here.

Just start watching the videos. You’ll start learning right away. Then look at the recommendations we make for recorded talks and books. Start building a small library of great recourses you can learn from and lend to others. Do it!

Here’s a sample of the kind of videos we have for you to watch: Bishop Robert Barron talking about The Theory of Everything, the Academy Award-Winning movie about atheist physicist Stephen Hawking.
