The funny part being that they write it as if the ideas are preposterous. Putting religion at the very basis of the operation of the universe is one hell of a drug.
EDIT: Already made it a comment, but I feel it's important before people get that idea that these people are necessarily our enemies.
People write/read takes like this and come to radically different conclusions due to their different base axioms of human experience. For the target readership of catholicculture.org, they are ones that are trying to understand the universe, with the base assumption being the existence of a Christian god. Many an apologetic has attempted to synthesize the real observable world with a just, righteous god. Regardless of their flawed logics, they are at least interested in taking a holistic approach to the human experience rather than an individual, capitalist, exploitative experience. As someone who as a child dove into the catholic theological worldview, desperate for meaning in this clearly meaning deprived society, these people can be radicalized, and are capable of changing their basis of thought. It takes real effort and patience, but they are much more likely to be a devoted comrade to the human liberatory unification experience than a bourgeois hedonistic individualist, who only cares for themselves and the people closest to them, who would rather not ponder their experience let alone the collective human experience, but rather live their own lives in pursuit of illusory happiness in isolation.
I think you're onto something here and reading up on this Liberation Theology , in particular how socialists that were eventually murdered were making big inroads with it in LatAm were applying it.
The " Preferential Option for the Poor " rhetoric is strong, not coded in left/right, has a third-way feel to it, and has potential to make a radical christian movement in favour of the most downtrodden. Learning this stuff is worthwhile if only for the fact that it arms you with rhetoric that can be used with the actually-well-read Christians. There is good rhetoric within this that is non-triggering and smartly coded to radicalise people leftwards without actually setting off their American red under the bed alarm bells.
