- Evolution. If evolution is true, there is no need for God.
Why? As St. Thomas Aquinas shows, any change has an associated causal chain that goes back to God. That includes such changes as mutations.
- When did the soul appear? If evolution occurred, then when was the soul created?
The soul appeared when the life appeared. The
rational soul appeared when humans appeared.
Were all ‘homo’ species provided with a soul, or only Homo sapiens?
What difference would that make? Both answers seem to be compatible with Catholicism, and there seems to be no reason to make a choice now.
- Bible. I’ve become rather despondent when listening to homilies, as time and again, I’m told the Bible stories I’ve believed as fact are actually theologically rather than historically accurate. if so, how can I still believe in the biggies like the resurrection?
You do not specify those “Bible stories”. Maybe you were right, maybe the priests saying the homilies were right.
In either case, it is the Church that tells us what Bible means.
- Miracles. Medicine is littered with stories of the power of the mind, and the placebo effect.
“Littered”?
You wouldn’t be exaggerating a little here?
And, as others have noted, placebo effect is not panacea.
- First cause. I struggle with the philosophical argument that everything that was created has a first cause. This doesn’t really work for me, because we’re still faced with God being eternal. (I know He’s not created, but that doesn’t really work for me).
Read “Summa Theologica” (
http://dhspriory.org/thomas/summa/index.html) and “Summa Contra Gentiles” (
http://dhspriory.org/thomas/ContraGentiles.htm) by St. Thomas Aquinas, perhaps following outline from blog post “Pre-Christian Apologetics” by Edward Feser (
Edward Feser: Pre-Christian apologetics).
You will see that after the arguments showing that “First cause” exists come arguments showing that it is eternal.
Then there are other things you can do.
First, have a look around in this forum. Seeing how an atheist makes a fool of himself might not be a very strong argument for Catholic faith, but it might still help.
Second, don’t worry too much if you cannot prove that God exists. What do you have to lose, if you choose to believe, even without 100% proof? See Pascal’s Wager, if necessary.
Third, don’t forget to pray.
And one more thing… Is there anything else that could be related to your problems with faith?
