So Francis probably could order the denial of communion to people who mistreat poor labourers - or who legalize mistreatment of poor labourers - but so far, he hasn't done this.
What do you suppose would be the likely political consequences to the Church of the Pope taking your advice? Do you think any 'interested parties' might seize on such an act in order to smear the Church as 'radical' or 'communist', and do you think the act would give their allegations credibility? Would there be any likely consequences to a sustained smear campaign against the Church in terms of the Church's overall influence on capitalists, CEOs, and politicians? Is denying communion a probable win situation for the Church?
Honestly, I have no answers. I'm not even really interested in the question (because it strikes me as too complex for discussion in this context). It's only that, if I were to genuinely look into the matter, I would at once get some sense or feeling that it was most likely more complex than it might look on paper.
He also has effective control of the assets of the Catholic Church, including the Vatican Bank, which he could use to weild economic influence for policy goals... but he doesn't do this.
I'm not familiar with the operations of the Vatican Bank. Could you be more specific please? I mean, specific relevant to your point.
