Marriage is to be an exclusive relationship .
It is well-known that many Old Testament believers had multiple wives, but this cannot be interpreted as prescriptive behaviour in light of the many commandments opposing this practice. A minister may marry two persons who do not confess and practice the Christian faith provided that they earnestly intend to adhere to the exclusiveness and permanence of marriage as required by God. The decision to marry two people who do not confess the Christian faith is based on the belief that forbidding such a union may be a greater evil in that this refusal may become a barrier to future belief in the Christian faith. Since the primary endeavour of all professing Christians should be conformity to the likeness of Christ, partnership with one who doesn't share such aspirations would only serve to hinder the professing Christian's realization of this goal. Simply put, a Christian is a believer and a follower of Jesus Christ.
