Thanks for your description of canon law (I presume thats what you mean) but I do remember a statement from some Catholic authority claiming Protestants were not real Christians (in the eyes of the church.)
It can be more than a little confusing. Any baptized Christian is considered to have joined himself to the Church "in a sense." For instance any baptized Christian could receive the Sacrament of Matrimony and be considered in a "Catholic Marriage", by marrying a Catholic in the Church.
Under extreme circumstances (immediate danger of death) I understand that any baptized person who professes a Catholic faith in these sacraments, could receive the Last Rites, including Confession, Communion and Anointing. I'm talking about true and immediate emergency.
These has been controversy about all this recently, because some of the Liberal/Modernist faction within the Church (e.g. certain loosey-goosey German Bishops) have proposed admitting Protestants to Catholic Communion if they are married to Catholics.
However, this can't be lawfully permitted because Marriage-to-a-Catholic is not a life-threatening emergency.
Ordinarily. :o/
