For we have seen His star in the East and have come to worship Him. And when he had gathered all the chief priests and scribes of the people together, he inquired of them where the Christ was to be born. And when they had come into the house, they saw the young Child with Mary His mother, and fell down and worshipped Him. An inclination and also a capacity for conjunction as though into one was implanted in man and woman from creation, and man and woman still have this inclination and capacity in them. Therefore they are no longer two, but one flesh.
Conjugial love joins two souls and thus two minds into one.
A wife's will unites itself with her husband's understanding, and the husband's understanding in consequence unites itself with his wife's will. In order that this union may be achieved, a wife is given a perception of her husband's affections, and also the highest prudence in knowing how to moderate them. This perception is a wisdom that the wife has. A man is not capable of it, neither is a wife capable of her husband's intellectual wisdom. According as the aforementioned conjunctions are formed, married partners become more and more one person.
