Personal mental health is achieved in and through contact with all of the others who struggle with the same demons as ourselves. Helping one another, we help ourselves. Community is required as well for the health of a society. In America our political decisions too often come down to selfish motives. These political judgments will rot our country from within, since they are based not on a proper sense of the common good, but on what's good for me and mine.
Good communities ask different questions of the larger body.
Every indication we can find in the gospels points to the Lord doing and preaching selflessness, kinship, and togetherness. He called individuals and immediately formed them into a school of apostles. He sent them out two by two. He took a group to the mountain of transfiguration and asked them all to go with him up to Calvary's height. He sent the women to announce his resurrection to all of the apostles and told them finally to go and baptize all nations-not all individuals.
