I think, based on the absence of any example of repentance among pro-abortion politicians, that their sin is far more cynical and cold-blooded than the sins of abortion mill workers or abortionists—who frequently become pro-life.
I would venture to say that “Catholic” pro-abortion politicians have committed the “sin against the Holy Spirit,” which is why they never repent. They can’t. They have entered the territory of the enemies of Jesus who plotted His death while KNOWING he was the Messiah. I.e., they can’t repent because they have KNOWINGLY committed the sin of calling manifest good evil and manifest evil good.
Thank you for challenging my perspective in a way that orients me toward the Holy Spirit. Peace be with you!
