“You have heard that it was said, Thou shalt not commit adultery. But I tell you that he who casts his eyes on a woman so as to lust after her has already committed adultery with her in his heart. If thy right eye is the occasion of thy falling into sin, pluck it out and cast it away from thee; better to lose one part of thy body than to have the whole cast into hell. And if thy right hand is an occasion of falling, cut it off and cast it away from thee; better to lose one of thy limbs than to have thy whole body cast into hell.” (St. Matthew v, 27-30)
“And now, brethren, I appeal to you by God’s mercies to offer up your bodies as a living sacrifice, consecrated to God and worthy of his acceptance; this is the worship due from you as rational creatures. And you must not fall in with the manners of this world; there must be an inward change, a remaking of your minds, so that you can satisfy yourselves what is God’s will, the good thing, the desirable thing, the perfect thing. (Romans xii, 1-2)
“Be not deceived: neither fornicators, nor idolaters, nor adulterers, Nor the effeminate, nor sodomites, nor thieves, nor the covetous, nor drunkards, nor railers, nor extortioners, shall possess the kingdom of God…. Know you not, that your bodies are the members of Christ?… Or know you not, that your members are the temple of the Holy Ghost, who is in you, whom you have from God, and you are not your own? For you are bought with a great price. Glorify and bear God in your body.” (I Corinthians vi, 9-10, 15, 19-20)
“And that is how husband ought to love wife, as if she were his own body; in loving his wife, a man is but loving himself. It is unheard of, that a man should bear ill-will to his own flesh and blood; no, he keeps it fed and warmed; and so it is with Christ and his Church; we are limbs of his body; flesh and bone, we belong to him. That is why a man will leave his father and mother and will cling to his wife, and the two will become one flesh. Yes, those words are a high mystery, and I am applying them here to Christ and his Church. (Ephesians v, 28-32)
