text: If you had ever been to a Christian wedding, you would have heard what "St. Paul", one of the first apostles to Christ, said in his Letters to the Corinthians.  Almost all the ministers start out with that text because it is the text about marriage in the New Testament.  He wrote those letters from Ephesus and Jesus' mother was supposed to be with him at the time.
  
  It talks about the immorality of sex outside marriage and such things.  
  
  1st Corinthians 7:1
  
  You can't get more "Christian" than that.
