Out of curiosity, why do you'all think that things like lay associations/secular orders/etc. developed in Catholicism and not in Orthodoxy? I mean, there are some groups here and there in Orthodoxy that are sort of/kinda similar, but nothing like what the Catholics have.

In the USA : GOYA, FOCA, SOYO, ACRY, Archons, OCF, YAM, LADIES PHILOPTOCHOS SOCIETY,Fellowship of Orthodox Stewards,Order of St. Ignatius,Antiochian Orthodox Christian Women of North America,SAINT ANDREW'S UKRAINIAN ORTHODOX SOCIETY, United Ukrainian Orthodox Sisterhoods, UOL,AROLA,ROYA and I am sure that I left off many others, please don't be offended, I just did a quick Google search.
