The Bible is clear that a Christian is never to marry a non-Christian.
The Old Testament specifically forbids God's people from marrying "foreign wives": "Now therefore, make confession to the LORD God of your fathers and do His will; and separate yourselves from the peoples of the land and from the foreign wives." ( So, the New Testament makes it clear that believers are only to marry fellow believers.
Although dating of Christians and non-Christians is not specifically handled in the Bible, it is clear that such an action is asking for trouble.
An unbeliever who practices Christian-like morality is going to be attractive to a Christian.
However, the chances that such a person will become a Christian, allowing the Christian to marry him/her is statistically remote.
I have received a few emails from Christians (and even one from a non-Christian) asking if it is okay for a Christian to date or marry an unbeliever.
Usually, by the time the question is asked, the relationship has gone far enough that a negative answer is going to be difficult to accept, even if it is the right answer.
Dating a non-Christian is also problematic, for similar reasons.
Those who marry an unbeliever prior to converting to Christianity are encouraged to stay with the unbeliever unless they leave.
