6348. 'because you went up to your father's bed' means because when separated from the good of charity faith is involved in a foul liaison. This is clear from the meaning of 'going up to his father's bed' as being involved in a foul liaison; that is to say, faith separated from charity is involved in it. For if faith in doctrine or the understanding, which 'Reuben' represents here, is not introduced to good and joined to it, it is either dissipated or ceases to be anything, or else it is introduced to evil and falsity and joined to them, which is the foul liaison that is meant. For then profanity comes about. The truth of this may be recognized from the fact that faith cannot have a dwelling-place anywhere else than within good; and if it does not have a dwelling-place there, then inevitably it ceases to be anything or is joined to evil. This is plainly evident from those people in the next life who have adhered to faith alone and not at all to charity. Their faith is dissipated in that life; or if it has been joined to evil, a lot among profaners awaits them.

[2] In the internal sense of the Word instances of adultery mean adulterations of good, while instances of whoredom mean falsifications of truth, 2466, 3399. But foul liaisons - which are called the forbidden degrees [of sexual relations], dealt with in Leviticus 18:6-24 - mean various kinds of profanation. Profanation is obviously meant here also since the words used are, 'You went up to your father's bed; at that time you profaned [it] - he went up to my couch'. Regarding the meaning of these words as the profanation of good by separated faith, see 4601, where that unspeakable deed performed by Reuben is dealt with.

[3] The nature of faith alone or faith separated from charity is such that if it is joined to evil - as happens when a person first believes the truth of faith, and especially when initially he leads a life in accordance with it but after that renounces it and leads a life contrary to it - profanity takes place. For the truth of faith and the good of charity first become rooted through doctrine and life in the person's interiors, after which they are called forth from there and are joined to evil. The lot that awaits the person in whom this happens is the worst of all in the next life; for with someone like that, good is incapable of being separated from evil, though they are nevertheless separated in the next life. Nor does someone like that have any remnants of good stored away in him interiorly because they have perished altogether in evil. Their hell is located on the left out in front, a considerable distance away; and those who are there look to the angels like skeletons, possessing scarcely any life. Therefore to avoid the occurrence of the profanation of goodness and truth, the person who - the Lord foresees - is the kind that will not allow himself to be regenerated is held back from faith and charity and is allowed to immerse himself in evil and consequently in falsity. For in this condition he cannot profane anything. See what has been stated and shown already about profanation in 301-303, 571, 582, 593, 1001, 1008, 1010, 1059, 1327, 1328, 2051, 2426, 3398, 3399, 3402, 3489, 3898, 4289, 4601.
