Why do we celebrate weekly communion? There are many good reasons but one of the most important is one we might not think about often enough—communion with the risen Christ also entails communion with others who are united to him by faith. Union and communion with our Lord leads us into union and communion with our brothers and sisters in the church, and (to a lesser extent) all people. John Calvin highlights this when he writes about the importance of communion. Calvin calls communion the “bond of charity” and explains, “For as the bread, which is there sanctified for the common use of us all, is made of many grains so mixed together that one cannot be discerned from the other, so ought we to be united among ourselves in one indissoluble friendship. What is more, we all receive there the same body of Christ, in order that we be made members of it.” For Calvin, communion with Christ is the foundation, and the motivation, for communion with others. This is one of our greatest motivations for mercy ministry—weekly communion reminds us of how much mercy God has poured out on us in His Son Jesus Christ. How can we hold anything back we see others in pain, in loneliness, in brokenness? Every week we participate in the sacrament of healing and wholeness, which equips us to be agents of the Kingdom in the lives of others.
