I don't think anyone who supports the strict interpretation would be able to tell the relatives of a catachumen that the catachumen is certainly damned because he was struck down without Baptism.
If the issue was just about baptism of desire of the catechumen, there would not exist any discussion.
Not according to the water Baptism alone crowd - no Baptism = no salvation. If there is only salvation for those who have received water Baptism then no catachumens who've died before Baptism can be saved.
That is too simplistic and misleading. The theory of baptism of desire of the catechumen, answers the question of what happens to a catechumen who is pre-sanctified (justified) before he is baptized, but dies before he can receive the sacrament of baptism.
St. Augustine is telling you that there is no such person, that the supposition is ridiculous, because God can complete what he started. Fr. Feeney said that he does not know where that person goes, and that neither do you. The BODer that knows his stuff, and the strict EENSer who knows his stuff, KNOW, that they can't answer otherwise. No one knows where such a person goes, or if there has ever been such a person at all.
