"in the nursery, taking lessons in modesty of deportment. What is the effect of this common mixing up? Does it increase chastity in the youth who thus gather together? No, indeed! it increases the first lustful passions; after such meetings the youth are crazed by the devil and give themselves up to their vile practices. 2T 482.1"
"Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,"
The EGW passage describes the increase of lustful passions and vile practices, which aligns with the list of 'works of the flesh' including adultery, fornication, uncleanness, and lasciviousness in Galatians 5:19. The connection is a thematic parallel.
"Parents are asleep and know not that Satan has planted his hellish banner right in their households. What, I was led to inquire, will become of the youth in this corrupt age? I repeat, Parents are asleep. The children are infatuated with a lovesick sentimentalism, and the truth has no power to correct the wrong. What can be done to stay the tide of evil? Parents can do much if they will. If a young girl just entering her teens is accosted with familiarity by a boy of her own age, or older, she should be taught to so resent this that no such advances will ever be repeated. When a girl's company is frequently sought by boys or young men, something is wrong. That young girl needs a mother to show her her place, to restrain her, and teach her what belongs to a girl of her age. 2T 482.2"
"Therefore let us not sleep, as do others; but let us watch and be sober."
EGW uses the phrase 'Parents are asleep' to describe their unawareness of the moral dangers facing their children. This directly echoes the call to watchfulness and sobriety in 1 Thessalonians 5:6, where being 'asleep' is contrasted with vigilance.
"Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light."
The EGW passage uses the metaphor of parents being 'asleep' to describe their lack of awareness of the moral dangers facing their children. This aligns with Ephesians 5:14, which calls on those who are 'sleepest' to 'awake' and receive light from Christ. The connection is a thematic parallel.
The corrupting doctrine which has prevailed, that, as viewed from a health standpoint, the sexes must mingle together, has done its mischievous work. When parents and guardians manifest one tithe of the shrewdness which Satan possesses, then can this association of sexes be nearer harmless. As it is, Satan is most successful in his effort to bewitch the minds of the youth; and the mingling of boys and girls only increases the evil twentyfold. Let boys and girls be kept employed in useful labor. If they are tired, they will have less inclination to corrupt their own bodies. There is nothing to be hoped for in the case of the young, unless there is an entire change in the minds of those who are older. Vice is stamped upon the features of boys and girls, and yet what is done to stay the progress of this evil? Boys and young men are allowed and encouraged to take liberties by immodest advances of girls and young women. May God arouse fathers and mothers to work earnestly to change this ter…
"Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband."
Both passages address the issue of sexual immorality. 1 Corinthians 7:2 suggests marriage as a way to avoid fornication. The EGW passage discusses the corrupting influence of inappropriate mingling of the sexes and the need to avoid it. While not a direct principle, there is a thematic parallel in addressing sexual purity.
