So you are not going to answer my questions?
Your questions have been answered through many readings of text and treatises but apparently you seek answers in conformance with what selections you choose to put forth.
But in a spirit of unity let me share with you a magnificent article written by America’s foremost Lutheran theologian, Rev. Richard Neuhaus (since passed away and founder of First Things) who converted to Catholicism.
This lecture for Christian unity between East and West was delivered at a leading Orthodox seminary.
I think you will agree with its overall tenor that draws from a symposium of speakers that included Orthodox theologians.
