Speaking of ecumenism, in "Orthodoxy and the Religion of the Future," Fr. Seraphim says that unity of all the Christian denominations naturally flows into unity of all world religions. For Orthodoxy to get with the flow, first she has to admit that she is one of the denominations. Membership in the WCC implies this admission of equality with the denominations. Only the jurisdictions which have not joined the WCC can understand this: that Orthodoxy shamefully denies her birthright by joining the WCC.
Towards this end, jurisdictional ecumenism strives for all the different anti-ecumenical jurisdictions to unite on an anti-ecumenism premise thus forming an immaterial "true church scoba." For Rocor, being mixed into the soup of "true" jurisdictions [some uncanonical, some schismatic, and some pseudo], this would mean giving up our birthright as the sole valid continuation of Rocor, which does have a special place in Orthodoxy. See the pattern?
