I call to memory the way Cardinal Burke was marginalized by Pope Francis merely for defending the Church's Teachings; see here and here. My blogging colleagues at Eponymous Flower and One Peter Five have some observations regarding this and the maltreatment of other faithful prelates such as Cardinal Pell, Cardinal Muller, Cardina Oullet, Cardinal Liovera. Read the EF piece for a description of how Cardinal Pell's work in trying to reform the Roman Curia is being deliberately undermined. In other cases, the faithful prelates are being snubbed by the pope in favor of heterodox prelates such as Cardinan Schonborn and Cardinal Kasper.
I find this whole thing to be quite Machiavellian. There are some who hold that the pope is just a naive little bumpkin who is being manipulated by the "evil bureaucrats in the Vatican". What will it take to remove the rose-colored glasses from their faces?
In the meantime we must pray and keep shining the light of truth on these machinations.
