I have heard angels speaking, through spirits, with those in the lowest hell, but this is done by means of spirits. And even though those who are there are at times let out of their prison for certain purposes, still there is such an abyss between hell and heaven, that they can never cross over. By the abyss [cf. Luke 16:26] is actually meant that it is utterly impossible for an infernal to come into a heavenly society, for they are completely repugnant to each other. 1748, 12 March.
