John Lane on Fr. Gleize's study:
"As for the theology of canonisation, and whether Fr. Gleize has a point, I maintain the general principle that the process is irrelevant to the security (and therefore the infallibility) of the judgement. Yet I think that the central point he drives at, which is the mysterious question of how a theological conclusion (or a fortiori a dogmatic fact) enters into the fabric of divine revelation (to borrow Mons. Fenton's excellent phrase), is a true mystery. Fr. Marin-Sola and others have debated this at length, and did not reach a consensus, so it's an open question in theology. Fr. Gleize's central point is absolutely the same question, couched in terms appropriate to the matter of canonisation. He is asking what mechanism, so to speak, is employed by the Holy Ghost, cooperating with men, to bring about the complete certitude that is required in order for a proposition ("this man is in heaven and his life, one of heroic not merely ordinary virtue, is to be venerated and imitated") to be "definable." You will have seen from that other thread that I don't find Fr. Marin-Sola's reasoning compelling, but even on my view the question is relevant, because if we are to have what is called purely ecclesiastical faith in a doctrine (e.g. a canonisation, a theological conclusion, a dogmatic fact), infallibly defined as these are, we must posit some theory as to how and why the Holy Ghost acts to bridge the gap between human judgement and divine certitude. On the foundation of the analogy with dogmas, I say that whatever the process, the result is still infallible. But the point I am making is simply this - can we say that Fr. Gleize is certainly wrong in the light of theology, or can we only say that our opinion differs with his. It's an important distinction."
