Faith, doubt, and science · Question 12
You claim to know every answer, then dodge with ‘mystery’ when you don't — right?

The question: “Can a believer explain the reason for everything that happens in the world?”
The Church's answer: In Jesus Christ, God has truly made known his own self and the purpose of his love, all that is needed for salvation. But no human being can fully fathom the infinite God and the whole of providence. Faith is not filling in the blanks with false certainty; it is a hope that holds on to the truth revealed and can still say “I don't know” humbly in front of mystery.
An analogy — a small window onto a wide horizon
Through a window you can see the actual sky, but you can't fit the whole sky inside the room. That what you see is true and that you have seen everything are two different claims.
The analogy shows that knowing truly in part is different from claiming to know it all. It doesn't shelter a poorly grounded claim by calling it “mystery”; whatever can be checked has to keep being examined.
If they press further: “If you don't know, isn't faith useless?” — you can know someone you love truly and be in a relationship with them without having analyzed them completely. Faith isn't an answer key to every riddle; it gives direction about whom to trust and how to love, even inside any suffering.
In one sentence: “Faith isn't a boast about knowing every reason. It's trusting the truth God has made clear, and hoping humbly in front of the mystery you don't know.”
