The "problem of evil"
Throughout the centuries theologians have racked their brains trying to explain how "evil" natural calamities can be permited by an absolutely sovereign God who is good and who is Love, without that making God evil.
ASSERTION: the "problem of evil" is no problem at all because it doesn't exist.
It is a chimera (illusion) born out of the self-righteousness of man.
Let us test the validity of the assertion with the fire of the WORD
1) Romans 3:23
All have sinned.
2) Romans 6:23
The wages of sin is death.
Since natural calamities execute the just reward of sin by causing death
and
Justice is not evil
We may conclude that
God is Just in allowing, indeed causing, such deadly calamities and therefore cannot be evil
It is not in vain that the Word says in Deutoronomy 32:4
He is the Rock, His work is perfect: for all His ways are judgment: a God of truth and without iniquity, Just and Right is He.
...and to think Aquinas could've been spared the trouble had he read the Bible.
