In The Four Loves, C.S. Lewis distinguishes between the four different types of love. They are Storge, Philia, Eros, and Agape.
Storge is the humblest of all loves, and is the least discriminating. It focuses on affection and is often related to the love between a mother and her child.
Philia is the least jealous of all loves, and possesses a certain "unnatural" quality. It is often related to the intense bond between friends who wish to seek a common truth together.
Eros is more commonly known as the love shared between two lovers. However, Eros has two parts-Eros and Venus. Venus is the carnal aspect of Eros, where a man desires a woman and seeks her for pleasure. Eros is the romantic and emotional side, where a man desires the woman and seeks her for who she truly is. Eros is the most appreciative of all pleasures, yet happiness is not its aim. The balance of giving and receiving is delicate and is only found by those who feel Eros, not just Venus.
Agape is love shown by God for His creation and love for God by creation. Our love for our Creator should be the focal point in all our relationships. No matter what we do, we should do it to honor and glorify God.
