From Catholic Herald:
The Pope has taken conservative bishops and cardinals to task for the way they dress, suggesting their adherence to ostentatious styles reveals a “rigidity” of mind that in some cases may even reach a level of “mental instability” and “emotional deviation”.
The Pope made his criticism of the sartorial preferences of traditional-leaning prelates, who have at times opposed his more liberal efforts at reform in the Church, in his autobiography titled Hope, which was published on 14 January, reports The Times. Their “rigidity”, he writes, “is often accompanied by elegant and costly tailoring, lace, fancy trimmings, rochets”, and which he described as amounting to “clerical ostentation”.
