“Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me”
“The pursuit of the common good is an aspect of personal discipleship but also part of God’s calling to the social and political structures.”
The pursuit of the common good, however, should not be detached from the worshipping and missionary life of the church “since the good cannot be fully realised apart from Christ, and Christ cannot be fully known outside the community of the faithful”. It can be the case that churches instead become pre-occupied with ‘domestic’ church concerns locally and nationally to the exclusion of this pursuit. Yet the distinctiveness of the Christian faith is in the idea of ‘incarnation’, the complete identification of God through Christ with humanity. Following Christ, therefore, also means living out this truth in relation to the people and communities around us.
The common good draws its real significance directly from the second great commandment ‘from which hang all the law and the prophets’: to love our neighbour as ourself. In the parable of the Good Samaritan we learn who is our neighbour, and in Matthew 25:34-45 we learn to see God in our neighbour: “Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me”. Therefore pursuit of the common good through Christian Community Action is responding directly to both of the two great commandments which lie at the heart of the Christian faith.
