What exactly is Fornication?
Fornication 'was' not simply "sex before marriage."
(In context) Fornication was the using of your body to have sex with a cultic temple prostitute to worship another god, deity. Giving your mind and body to worship another deity. To worship a fertility god so they could have the promise to get good farm crops.
Though the standing English definition for fornication was stated correctly in the previous post, through translation it has lost the original meaning. There is no doubt that fornication, now and then, was "sex before marriage" sometimes better defined as "sex without marriage." I will list a few bible verses below that will explain the 'in context definition' of fornication.
1Co 10:8 - Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand. (these people where idol worshippers.)
Re 2:20 - (these people were idol worshippers.) Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols.
Re 2:14 - (these people were idol worshippers.)
But I have a few things against thee, because thou hast there them that hold the doctrine of Balaam, who taught Balac to cast a stumblingblock before the children of Israel, to eat things sacrificed unto idols, and to commit fornication.
I admit, I cannot verify my findings. I am not a Hebrew scholar, who could actually look at the original scripts to verify such. I merely wish to present very logical ideas that will lead us to the truth.
