This seems to be a very topic of interest to Catholics. Frequently it is asked on this site. But I do not yet understand why you think this is significant matter. You believe your holy sacraments are valid (a very legalistic expression to mean that ? I suppose God is acting through them to save person). Why do you care if Orthodox officially make some statement about Your Sacraments validness.?? This is not business of our Church to make statements about such matters. Believe in your Holy Sacraments. We believe in ours! Our Lord will be judge if there is some legal problem. But why expect Orthodox Church to make some statement about your Church services??? If I am not understanding point, please explain to me.
