[from the New Testament Institute manual, section entitled (39-5) Romans 1:26, 27. How Serious Is the Sin of Homosexuality?]
“Of the adverse social effects of homosexuality none is more significant than the effect on marriage and home. The normal, God-given sexual relationship is the procreative act between man and woman in honorable marriage. . . .
“. . . where stands the perversion of homosexuality? Clearly it is hostile to God’s purpose in that it negates his first and great commandment to ‘multiply and replenish the earth.’ If the abominable practice became universal it would depopulate the earth in a single generation. It would nullify God’s great program for his spirit children in that it would leave countless unembodied spirits in the heavenly world without the chance for the opportunities of mortality and would deny to all the participants in the practice the eternal life God makes available to us all.
“Because of the seriousness of this sin it carries a heavy penalty for the unrepentant. The offender may realize that disfellowshipment or excommunication is the penalty for heavy petting, adultery, fornication and comparable sins if there is not adequate repentance, yet he often supposes that because his acts have not been committed with the opposite sex he is not in sin. Let it therefore be clearly stated that the seriousness of the sin of homosexuality is equal to or greater than that of fornication or adultery; and that the Lord’s Church will as readily take action to disfellowship or excommunicate the unrepentant practicing homosexual as it will the unrepentant fornicator or adulterer. . . .
“After consideration of the evil aspects, the ugliness and prevalence of the evil of homosexuality, the glorious thing to remember is that it is curable and forgivable. The Lord has promised that all sins can be forgiven except certain ones enumerated, and this evil was not among those named. Thus it is forgivable if totally abandoned and if the repentance is sincere and absolute. Certainly it can be overcome, for there are numerous happy people who were once involved in its clutches and who have since completely transformed their lives. Therefore to those who say that this practice or any other evil is incurable, I respond: ‘How can you say the door cannot be opened until your knuckles are bloody, till your head is bruised, till your muscles are sore? It can be done.’
“. . . Many have been misinformed that they are powerless in the matter, not responsible for the tendency, and that ‘God made them that way.’ This is as untrue as any other of the diabolical lies Satan has concocted. It is blasphemy. Man is made in the image of God. Does the pervert think God to be ‘that way’? . . .
“Sometimes not heavenly but earthly parents get the blame. Granted that certain conditions make it easier for one to become a pervert, the second Article of Faith teaches that a man will be punished for his own sins. He can, if normal, rise above the frustrations of childhood and stand on his own feet. . . .
“A man may rationalize and excuse himself till the groove is so deep he cannot get out without great difficulty. But temptations come to all people. The difference between the reprobate and the worthy person is generally that one yielded and the other resisted. And if the yielding person continues to give way he may finally reach the point of ‘no return.’ The Spirit will ‘not always strive with man.’ (D&C 1:33.)”
