Fellowship can be something that brings God's people together, as well as something that can destroy the church.
The entire Christian faith centers around creating and strengthening our relationship with God and with other believers (Acts 2: 42-47). Eating with another person is an intimate thing, because eating is something needed for survival.
Church becomes a mundane experience where our instincts kick in. We stand up when worship starts or for the scripture reading. We close our eyes and lift our hands the moment the beat drops and start to sway side to side as we are lead into "worship." In this moment we are becoming like animals who follow their instincts.
