What is Carlo Maria Viganò's religious order? I was wondering in which religious order did Viganò got ordained as a priest (is he franciscan, jesuit, dominican)?
According to catholic-hierarchy.org Carlo Maria Viganò was ordained as priest of the diocese of Pavia on 24th of March 1968.

So he was a (normal) diocesan priest before becoming bishop and is no member of any order.
