Note 23 — IV THE ESSENCE OF CATHOLICISM
J. E. Crawford (John Ernest Crawford) Flitch translation
The allusion is to the traditional story of the coalheaver whom the devil sought to convince of the irrationality of belief in the Trinity. The coalheaver took the cloak that he was wearing and folded it in three folds. "Here are three folds," he said, "and the cloak though threefold is yet one." And the devil departed baffled.—J.E.C.F.
