His Lordship is wearing a plain surplice sans stole rather than a rochet and manteletta. Did he forget to pack for his trip or was he caught off guard? Oh well, the SSPX bishops are always going about in mozzettas which they ought not to do. The mozzetta was a jurisdictional garment prior to Montini's 1960s changes to prelatial vesture. Now a mozzetta is ubiquitous amongst Novus Ordo bishops.
