The quote from TUB you referenced is interesting in light of the UB's emphasis on equality of the sexes. . . . . While I don't doubt that Hap gave such counsel at the time, and that it was beneficial for the society and the culture in which it was given, I am not 100% certain that it fits our current society.

Word Origin and History for adultery
n.

"voluntary violation of the marriage bed," c.1300, avoutrie, from Old French avouterie (12c.), noun of condition from avoutre, from Latin adulterare "to corrupt" (see adulteration ).

143:5.3 Jesus replied: “Everyone who drinks of this water will thirst again, but whosoever drinks of the water of the living spirit shall never thirst.

And this living water shall become in him a well of refreshment springing up even to eternal life.” Nalda then said: “Give me this water that I thirst not, neither come all the way hither to draw. Besides, anything which a Samaritan woman could receive from such a commendable Jew would be a pleasure.” *

143:5.4 Nalda did not know how to take Jesus' willingness to talk with her. She beheld in the Master's face the countenance of an upright and holy man, but she mistook friendliness for commonplace familiarity, and she misinterpreted his figure of speech as a form of making advances to her. And being a woman of lax morals, she was minded openly to become flirtatious, when Jesus, looking straight into her eyes, with a commanding voice said, “Woman, go get your husband and bring him hither.” This command brought Nalda to her senses. She saw that she had misjudged the Master's kindness; she perceived that she had misconstrued his manner of speech. She was frightened; she began to realize that she stood in the presence of an unusual person, and groping about in her mind for a suitable reply, in great confusion, she said, “But, Sir, I cannot call my husband, for I have no husband.” Then said Jesus: “You have spoken the truth, for, while you may have once had a husband, he with whom you are now living is not your husband. Better it would be if you would cease to trifle with my words and seek for the living water which I have this day offered you.”

143:5.5 By this time Nalda was sobered, and her better self was awakened. She was not an immoral woman wholly by choice. She had been ruthlessly and unjustly cast aside by her husband and in dire straits had consented to live with a certain Greek as his wife, but without marriage. Nalda now felt greatly ashamed that she had so unthinkingly spoken to Jesus, and she most penitently addressed the Master, saying: “My Lord, I repent of my manner of speaking to you, for I perceive that you are a holy man or maybe a prophet.” And she was just about to seek direct and personal help from the Master when she did what so many have done before and since—dodged the issue of personal salvation by turning to the discussion of theology and philosophy. She quickly turned the conversation from her own needs to a theological controversy. Pointing over to Mount Gerizim, she continued: “Our fathers worshiped on this mountain, and yet you would say that in Jerusalem is the place where men ought to worship; which, then, is the right place to worship God?”

143:5.6 Jesus perceived the attempt of the woman's soul to avoid direct and searching contact with its Maker, but he also saw that there was present in her soul a desire to know the better way of life. After all, there was in Nalda's heart a true thirst for the living water; therefore he dealt patiently with her, saying: “Woman, let me say to you that the day is soon coming when neither on this mountain nor in Jerusalem will you worship the Father. But now you worship that which you know not, a mixture of the religion of many pagan gods and gentile philosophies. The Jews at least know whom they worship; they have removed all confusion by concentrating their worship upon one God, Yahweh. But you should believe me when I say that the hour will soon come—even now is—when all sincere worshipers will worship the Father in spirit and in truth, for it is just such worshipers the Father seeks. God is spirit, and they who worship him must worship him in spirit and in truth. Your salvation comes not from knowing how others should worship or where but by receiving into your own heart this living water which I am offering you even now.”

143:5.7 But Nalda would make one more effort to avoid the discussion of the embarrassing question of her personal life on earth and the status of her soul before God. Once more she resorted to questions of general religion, saying: “Yes, I know, Sir, that John has preached about the coming of the Converter, he who will be called the Deliverer, and that, when he shall come, he will declare to us all things"—and Jesus, interrupting Nalda, said with startling assurance, “I who speak to you am he.”
