double consecration. therefore even if he was a mason, its still valid.
That argument does not work as +Liénart alone
ordained +Lefebvre. Majority of theologians held that one can not be consecrated a bishop without first having been ordained a priest.
I would look into the allegations of +Liénart being a freemason. From what I understand they are at best questionable, having appeared (without a source(?) shades of
The Angelus??) in a later edition of the list of Freemasons in the Church hierarchy...although +Lefebvre *
allegedly* stated that he believed +Liénart to have been a Freemason (
*allegedly* in speeches on May 11, 1976 in Minneapolis, MN and May 27, 1976 in Montreal, Québec) and +Williamson did in EC No. 450 "Bishops Valid? -II" Feb. 27, 2016: "The Cardinal [Liénart] was a leading neo-modernist at Vatican II, and surely a Freemason himself."
