“Ever since the publication of Fiducia supplicans, the controversial declaration the Vatican’s doctrinal office issued last December that allows priests the possibility of blessing same-sex couples, Martin proudly states he has done so four times.” I don’t think Fiducia Supplicans allows a priest to bless the union of a homosexual couple.
And, while I’m no expert, I am fairly certain your post saying “every time a Catholic priest/bishop blesses a homosexual couple they are blessing the sin; not the individuals” is incorrect. In fact I believe it is the exact opposite. They are blessing the individuals not the sin and not the couple.
