(Extra credit for reading the whole chapter! Extra extra credit for reading the whole book!!)
I really hope that this is playful and not some subtle way to imply that Catholics are Catholic because they haven’t read Romans.
Anyways, to get to the question:
Does Pharaoh have free will?
In the Exodus story, prior to any mention of God hardening Pharaoh’s heart, we see Pharaoh hardening his own heart (i.e. being stubborn) after the second plague (Ex. 8:11 - NABRE, 8:15 - ESV) and fourth plague (Ex. 8:28 - NABRE, 8:32 - ESV). Other external references to Exodus also reference it as Pharaoh’s doing (e.g. 1 Samuel 6:6). As such, it is reasonable to see Pharaoh as possessing free will.
What do you think about the potter and the clay?
As created beings, it is incredible insolent on our part to judge God as if He were like us. Paul isn’t so much answering the objection directly - how does sin exist if God is sovereign? - but pointing out the underlying arrogance on display, an arrogance that was at the core of much of Rome’s problems at the times. It’s entirely valid to see the comments less as a commentary on how God actually interacts with humans and how arrogant humans tend to be when judging God.
However, even when considering God’s sovereignty over His creation, Molinism is just as compatible with the passage as Calvinism, to provide one example of a non-Calvinist reading.
What does this passage say about God?
Bear in mind one of the core problems facing Rome at the time. Judaizers were professing that they could somehow bring God’s grace upon them through their works, most notably through enforcing circumcision. The problem can also be seen in both Acts 14-15 and the book of Galatians. Of course, such a belief is incompatible with how God offers grace, and the very idea that we can earn God’s favor is actually quite arrogant.
This passage is really attacking that arrogance. We cannot earn mercy, as that is God’s to give and withhold as He pleases. In fact, there are cases where God withholds mercy for some reason (e.g. Pharaoh) or offers it to one over another (e.g. Jacob and Esau). By the time we reach the potter and clay, Paul is practically mocking the Judaizers.
Ultimately, it lays out a couple things about God:
- God is ultimately sovereign and can do what He wants with His creation.
- Mercy is God’s to give and God’s to withhold. We cannot force His hand or judge Him for how He gives it out.
What the passage does not discuss about God is
how He goes about giving out grace and mercy.
How can we see God’s love in this passage?
Check out verses 23-26.
How does the Catechism address this passage?
The only two verses in Romans 9 cited anywhere in the Catechism are verses 4-5.
