But that concept may be based more on culture than Scriptural evidence. Some of God s principles may be applied differently in different cultures. From the beginning of our history in Genesis, it seems that God s intention was that a man have only one wife. Such a perceived law is derived only from our legalistic logic. Those answers do not fit.
Fornication is sexual relations of two unmarried persons.
Sexual relations outside of marriage between two people, with one or both being married, is adultery. Neither of those definitions fits the polygamist, for he is married to the women involved. A man cannot commit adultery with his wife. It seems strange that no case is made against receiving such a man when he wished to accept the Gospel. And no preacher or writer of New Testament record registers disapproval or rejection of such a person having the two wives.
