Are we aware that there must be a gathering when a priest celebrates the Eucharist  ?  
It requires a special dispensation for the " private " celebration by a priest  all by himself  .
 The proclamation is    "the Mystery of Faith "  as the signs of bread and wine now consecrated are elevated  .  
But leave it to Jesus who repeatedly shows himself disguised! !!   
Francis just said reform is irreversible.   So why the so-called Orthodox catholic position defying a Council , a Pope and the Holy Spirit  ?  

A thousand years ago calling yourself an Orthodox catholic was enough to get yourself killed if not by Catholics then definitely by the Orthodox!
