As ever do the previous steps taken down a slippery slope...
Thanks for the explanations.
The slippery slope was done sliding a long time ago, as you of course know.
What is left in ECUSA are a bunch of priests and bishops (and laymen) who have made their peace with a whole lot of things fully contrary to Christian tradition.
If one can make ones peace with the ordination of women to the diaconate (the ancient order of deaconesses was never the same as that of the deacon) and the priesthood, let alone to the episcopacy, then one has decided that Christian tradition can be dispensed with and that the Scriptures can be treated as a "living document" cut free from the clear evidence from Christian tradition on how the Scriptures are to be interpreted.
If one can make ones peace with a church that accepts as acceptable abortion and homosexual activity on the part of the laity, ditto.
It is not that I don't have sympathy for the remaining strugglers in ECUSA, but they have long ago given away the ground needed in order to make credible defenses for the positions they want to try to hold the line on.
I personally do not see how arguments can be effectively and irrefutably made "Sola Scriptura" against any of these ills. Only by treating Tradition as authoritative can one render all of the liberal arguments moot. This is why we aren't having any of these arguments in Orthodoxy.
