We screwed up NOTHING, everything happening according to God’s original design/ plan.
If God would not will sin, He would created this world in which evil and sins (original and ours) would have no place.
In fact, God DESIGNED/ PLANNED, PREDESTINED from all eternity, ORDERED and CAUSED the original sin, and they are FREELY chosen their “sins/ fall.”
The same above principle applies the sins we are all FREELY commit as well, of course CAUSED by God. – CCC 308; etc. Far from diminishing our dignity, this truth enhances it.
Without God, His cooperation by providing the power of operation for our acts of sins, the acts of our sins predestined from all eternity in accordance with His all-embracing purpose, we can do absolutely NOTHING, not even a smallest act of sin.
Catholic Encyclopedia : Evil
“But we cannot say without denying the Divine omnipotence, that another equally perfect universe could not be created in which evil would have no place.”
310 But why did God not create a world so perfect that no evil could exist in it?
God freely willed to create a world in a state of journeying towards its ultimate perfection, 314 through the dramas of evil and sin .
As we see above, God does not only not will sin, but He created in this world the dramas of evil and sin and this is what HE CREATED at His CAUSE of the “fall.”
The TECHNICALITY the way God step by step made the events happened at the “fall,” the way God step by step created the dramas of evil and sin .
At the “fall,” God removed our heart of flesh and put a heart of stone instead. – Reverse of Ez.36:26.
God made the “fallen” man/ us carnally minded, God also made us unable to subject to His law, (Rom.8:6-7).
God infused the “fallen” man/ us with the law of sin/ God enslaved us to sin, to all manner of evil desire, the inclinations for all kinds of sins, (Rom.7:8-23). etc.
As we see, it is an absolute logical fallacy to say God does not will sin, when at the “fall” He has created the dramas of evil and sin.
CATHOLIC ENCYCLOPEDIA Divine Providence explains;
“His wisdom He so orders all events within the universe that the end for which it was created may be realized.
He directs all, even evil and sin itself, to the final end for which the universe was created.”
Nor would God permit evil at all, unless He could draw good out of evil (St. Augustine, “Enchir.”, xi in “P.L.”
Evil, therefore, ministers to God’s design (St. Gregory the Great, op. cit, VI,
324 Faith gives us the certainty that God would not permit an evil if he did not cause a good to come from that very evil, by ways that we shall fully know only in eternal life.
As we see; Sin is not rebellion against God, sin is ministers to God’s design and He created the dramas of evil and sin, for the benefit of the entire human race.
