34. (19) Conjugial love depends upon the wife's love, and such too is the husband's love reciprocally; the wife's love does not depend on her husband's love. The reason is that just as the will acts on the understanding, good acts on truth; that is why it is said that a man ought to cleave to his wife. The reverse is true of those who are not in conjugial love.

2507. 'Of Sarah his wife' means spiritual truth joined to the celestial. This is clear from the meaning of 'Sarah his wife' as intellectual truth joined to Divine Good, or what amounts to the same, spiritual truth joined to the celestial, dealt with in 1468, 1901, 2063, 2065, 2172, 2173, 2198. What the spiritual is, and what the celestial, has been stated quite often already, see 1155, 1577, 1824, 2048, 2088. That is called the celestial which consists in good, that is, which consists in love to the Lord and in charity towards the neighbour; and that is called the spiritual which consists in truth, that is, which consists in faith deriving from love and charity.
