One thing the members of the Movement are going to have to deal with is the use of their history as the eternal illustration of [insert scandalous defect here] by the Church and the wider world. A perfect example is this article by Mark Shea:
One of the big puzzles that many Catholics have grappled with in recent years is the baffling phenomenon of some charismatic figure (one thinks of a Rev. Marcial Maciel, for instance) who can, for years, inspire or otherwise offer blessing and solace to good and decent Christians who are full of faith and obedient to the Church. Said figure can preach or write clear and engaging explications of the Faith. He can do all sorts of wonderful things that help struggling souls find healing, that give new purpose to the hopeless, and that help the lost discover the riches of grace in Christ. He is beloved by his devotees– and not without reason.
And yet that charismatic figure then turns out to be bound up with very serious sin or even shown to be, as in Father Maciel’s case, a monster of diabolical proportions.
Mark goes on to make some excellent points, which are up for discussion here, but the larger lesson is that as long as the Legion and Regnum Christi exist, they will stand as a stark reminder of betrayal: betrayal of the innocence of particular young men over many years, betrayal of various women and children begotten by Maciel, betrayal of the Church that welcomed members of this Movement with its dark agenda, betrayal of those who were smeared and slimed for revealing the truth, betrayal of countless Catholics who offered them their money and their children, and betrayal of several Holy Fathers who mistakenly approved their toxic methodology [well-deserved correction here].
Current members can insist that THEY weren't part of the problem, THEY mean well, THEY are sincere Catholics who simply want to be part of the New Evangelisation -- but they cannot rewrite history. They can be a Congregation with a nameless founder, a corps of believers with no charism, mission or approved rule, but as long as they insist on working AS Legionaries or members of Regnum Christi, they are saying that they choose to do this work under the banner of a corrupt institution. They insist that Christ isn't enough: it must be Christ filtered through the compromised kiss of Judas.
Why isn't Christ enough? Christ filtered through Francis is understandable; as is Christ through the prism of Ignatius, Dominic or Teresa of Calcutta. What remains of Maciel's filter that cannot be done better without it? Or to reverse the question, What is it about Maciel's filter that helps the Church.
Maciel's illustration will ever be a blot on history -- on the Curia, on the Pope, and on the Congregation itself. They will always be the "go to" example of "what went wrong?"
Shame and eternal shame, nothing but shame! (Henry V, Act 4, Scene 5)
UPDATE: Another site asks essential questions about the ongoing existence of the Legion, and reminds us that we cannot clean house without going to the root of the scandal: Who knew what, when? If we learned nothing else from Boston, didn't we learn that until the truth is exposed, it will fester and harm the Mystical Body? There is the eternal illustration, and then there is the ongoing vague distrust of the entire Curia. In essence, this scandal unjustly tarnishes all of its members until an investigation distills the facts, and isolates those who are to blame.
