As I was perusing the Legion site, seeing what numbers and apolostolates they're still visibly associated with (more stealth works remain), I saw that under "Education" they claim an association with the JP2 Pontifical Institute for Marriage and Family. This is ... curious, to say the least. I never before realised that there was a link, and so I looked at the school's official site.
Since many works use the previous Pontiff's name in their titles, I thought maybe there were two. But they're both Pontifical institutes (that's a BIG deal), both founded in 1981, and they share all the other details. The school itself has no board members who are LC, no listed profs or alumni that would explain the claim, and wasn't started by the Legion, I am wondering what their reason for claiming the schools as one of their "works" (along with the schools that they do run):
We have to let Jesus Christ reign in man’s heart, mind, and life. The specific mission of the educational institutions of the Legion and Regnum Christi is to form integral people, working together with their families, so that they will be leaders of positive action and convinced builders of the civilization of justice and love according to the principles of Christian humanism. This is the ideal summed up in the motto “Integer Homo”.
The only justification might be that they send some of their members to the school. That's nice. But then we seem to have some serious obfuscation concerning the Legion's real association.
[This school (in the surveying stage) relies on the same Integral Formation noted on the LOC page and links to NCE -- a distinct L/R brand, but offers no other visible link. If indeed, this is not a school associated with the Legion (and certainly they are not known for the Trivuum methodology) then they should be very careful, since the Legion has trademarked the concept "Integral formation."]
