Three Loves is a brief look at the three kinds of love involved in dating, courtship, and marriage. C.S. Lewis, in his book, The Four Loves, proposes that there are four kinds of love based on classical Greek. However, only two of his Greek words for love are found in the Bible. For the purpose of looking at the love between a man and a woman, it makes sense to look at three kinds of love: romantic, committed, and sexual.
