In these two scriptures we have a complete definition of unchastity. The seventh commandment, with the Saviour's commentary upon it, places clearly before us the fact that chastity requires purity of thought as well as of outward acts. Impure thoughts and unchaste acts are alike violations of the seventh commandment. As we shall see, also, unchastity of the mind is a violation of natural law as well as of moral law, and is visited with physical punishment commensurate to the transgression.
[Mental Unchastity.]—It is vain for a man to suppose himself chaste who allows his imagination to run riot amid scenes of amorous associations. The man whose lips delight in tales of licentiousness, whose eyes feast upon obscene pictures, who is ever ready to pervert the meaning of a harmless word or act into uncleanness, who finds delight in reading vivid portrayals of acts of lewdness,—such a one is not a virtuous man. Though he may never have committed an overt act of unchastity, if he cannot pass a handsome female in the street without, in imagination, approaching the secrets of her person, he is but one grade above the open libertine, and is as truly unchaste as the veriest debauchee.
Man may not see these mental adulteries, he may not perceive these filthy imaginings; but One sees and notes them. They leave their hideous scars upon the soul. They soil and mar the mind; and as the record of each day of life is photographed upon the books in Heaven, they each appear in bold relief, in all their innate hideousness.
O purity! how rare a virtue! How rare to find a face which shows no trace of sensuality! One turns with sadness from the thought that human "forms divine" have sunk so low. The standard of virtue is trailing in the dust. Men laugh at vice, and sneer at purity. The bawdy laugh, the ribald jest, the sensual glance, the obscene song, the filthy tale, salute the eyes and ears at every street corner, in the horse-car, on the railroad train, in the bar-room, the lecture hall, the workshop. In short, the works and signs of vice are omnipresent.
Foul thoughts, once allowed to enter the mind, stick like the leprosy. They corrode, contaminate, and infect like the pestilence; naught but Almighty power can deliver from the bondage of concupiscence a soul once infected by this foul blight, this moral contagium.
Mental Uncleanness.—It is a wide-spread and deadly error, that only outward acts are harmful; that only physical transgression of the laws of chastity will produce disease. We have seen all the effects of beastly abuse result from mental sin alone.
"I have traced serious affections and very great suffering to this cause. The cases may occur at any period of life. We meet with them frequently among such as are usually called, or think themselves, continent young men. There are large classes of persons who seem to think that they may, without moral guilt, excite their own feelings or those of others by loose or libidinous conversation in society, provided such impure thoughts or acts are not followed by masturbation or fornication. I have almost daily to tell such persons that physically, and in a sanitary point of view, they are ruining their constitutions. There are young men who almost pass their lives in making carnal acquaintances in the street, but just stop short of seducing girls; there are others who haunt the lower classes of places of public amusement for the purpose of sexual excitement, and live, in fact, a thoroughly immoral life in all respects except actually going home with prostitutes. When these men come to me, laboring under the various forms of impotence, they are surprised at my suggesting to them the possibility of the impairment of their powers being dependent upon these previous vicious habits."[4]

"Those lascivious day-dreams and amorous reveries, in which young people—and especially the idle and the voluptuous, and the sedentary and the nervous—are exceedingly apt to indulge, are often the sources of general debility, effeminacy, disordered functions, premature disease, and even premature death, without the actual exercise of the genital organs! Indeed, this unchastity of thought—this adultery of the mind—is the beginning of immeasurable evil to the human family."[5]
