Dr. Gareth Icenogle writes,

“From the beginning of human history, the eternal God in Community created humanity as community. Humanity reflects the eternal community of God as man and woman together with God. These three form the primeval small group of human history. The minimum group of two, together with the Community of God, is called to live in intimate, reciprocal, dialogical and growing relationship. Around this prototype small group of the first divine-human community, God has gathered the greater human community of history.” (Biblical Foundations for Small Group Ministry: An Integrative Approach)

Who would have thought that marriage is a pointer towards small group ministry?
