It would be humorous if it were not so disturbing how so-called traditional orthodox eschew "other-than-Roman-Catholic" persons, denominations. Of course they do not hold to "all" that we hold and to talk of "apostolic succession" and "valid/licit orders", Sacraments, "Henry VIII, Luther, and fellow congregation founder/leaders as somehow "intrinsically dis-ordered" is uncivil AND unChristian.
As to Eucharist, one can and does ask: if God is & Jesus lives, everywhere, in/of all things then how is it that "only we" can access Him and his "amazing", redemptive grace?  Some of us have even quoted, sort of, Vatican II "testifying" that Protestant Churches are not Churches!
Brothers and sisters it matters. Do you really believe that God the Parent, Jesus the Word and the "Holy Spirit" are not "big" enough to include all in the same embrace of redemption as "They" did and do in creation?  
We are simply unworthy heirs of a grand tradition, a grand tradition that has gone terribly awry.
