A bishop has complete authority in his diocese.
“A bishop has complete authority in his diocese.”
Exactly, and the bishop in question is Lopez and not Garcia-Siller. You see, Garcia-Siller is the bishop of the diocese, but Lopes is the bishop of the ordinariate. Thus, if the nuns could gain membership in the ordinariate, then they could permanently stay at Our Lady of the Atonement Catholic Church and there’s not a damn thing Archbishop Garcia-Siller could ever do about it.
You do realize that the ordinariate is it’s own diocese really, right? The parish in question - Our Lady of the Atonement Catholic Church - separated from the diocese last year and joined the ordinariate. Archbishop Garcia-Siller has NO AUTHORITY over the parish. NONE. He can, however, exert authority over the nuns since they are not members of the ordinariate.
