democratic-christianism actually, which besides its traditionalism does have something of a left looking streak

But you will note that Catholic Social Doctrine can be seen as a late-19th-century attempt by the Church to remain relevant in the face of the rise of the socialist workers' movement.

So that "left-leaning streak" is also a consequence of the Industrial Revolution. And, just like the Social Democrats have colonised the Social-Liberal space, the Christian Democrats have become neoliberal.
