Yes, I think that is where it is going. Similar to the Orthodox, who add to Tertulian's notion, expand upon it. In his book, ORTHODOXY, Orthodox Bishop Ware notes: "For Orthodoxy, the validity of ordinations does not depend SIMPLY on the fulfillment of certain technical conditions (external possessions of the apostolic succession; correct form, matter and intention). The Orthodox also ask: What is the general sacrament teaching concerning the inner meaning of the apostolic succession and the priesthood? How does it understand the Eucharist?" etc. This is very similar to Cardinal Kasper's understanding. To compound matters, it is hard for Catholic ecumenists to know exactly which voice speaks for the Anglican Communion, given its brokenness among bishops, etc. Some Anglicans bishops don't accept lay presidency; others do (in Australia). Some don't accept gay civil unions among clergy; others do. Some don't accept women bishops; others do. Same with other moral and doctrinal issues.
