Porneia (fornication) "is used of illicit sexual intercourse…." [W. E. Vine,
Expository Dictionary of New Testament Words]
Fornication: "illicit sexual intercourse in general … distinguished from adultery (
moicheia) in
Matthew 15:19 … used of adultery … in
Matthew 5:32;
19:9 [Henry Thayer,
Thayer's Greek-English Lexicon, pg. 532].
Fornication: "The New Testament is characterized by an unconditional repudiation of all extra-marital and unnatural intercourse" [
Theological Dictionary of the New Testament, Vol. 6, pg. 590].
I know of no reputable Greek lexicon or dictionary which includes pornography or masturbation as a part of the definition of
porneia.
One can also go through the Septuagint translation of the Old Testament to see what Hebrew words were translated to
porneia to get an idea of what the word meant. You will find:
The actual Greek word for masturbation was
anaphlan, which does not appear in the Bible.
As I pointed out in "
Is masturbation sinful or not?" the act of masturbation would fall underneath one category of uncleanness, that of ejaculation. Unclean things in themselves, such as pigs, death bodies, menstrual periods, etc., were not sinful in and of themselves. Breaking the laws in dealing with unclean things was sinful. Since God did not define the act of masturbation as sinful, nor as righteous, it would be sinful to add or subtract from what God said. Instead, we look at what typically accompanies masturbation and there we find plenty of things to talk about why those accompanying things are wrong. But even here, the accompanying sinful things, such as pornography, are sinful because the Bible condemns pornography (
I Thessalonians 4:5), not because someone wants to twist the definition of
porneia to include pornography.
FATHER GOD I COME TO YOU IN THE NAME OF JESUS STANDING AGAINST THE SPIRIT OF 'LUST' THAT THIS INDIVIDUAL NOT BE OVERTAKEN BY THE GRATIFICATION OF THE MIND, BODY, AND SOUL. I TAKE AUTHORITY IN THE SPIRIT REALM OVER THIS SPIRIT AND LOOSE IT OF ITS ASSISGNEMENT ON THIS PERSON'S LIFE AND COMMAND IT TO BE DISMISSED FROM THE MERE SPHERE OF INFLUENECE ON THEIR LIFE AND DESTINY BACK TO THE ABYSS. I COMMAND ANY DEVIVES LEFT BEHIND POWERLESS AND THAT ALL MEMORIES DEPOSITED IN THEIR MIND, BODY, AND SPIRIT BE ERASED IN THE NAME OF JESUS AND THIS SOUL IS SET FREE FROM ALL SELF-GRATIFTING ACTIVITIES IN THE NAME OF JESUS. I LOOSE THE SPIRIT OF LOVE AND PEASE IN THE ATMOSPHERE THAT THE LOVE OF JESUS SHALL SUSTAIN ALL SOUNDNESS TO THE MIND AND THE BODY SHALL BE CALMED AND RELAXED TO SERVE THE ALMIGHTY GOD, IN THE NAME OF JESUS. AMEN.
