This is the rule of the most perfect Christianity, its most exact definition, its highest point, namely, the seeking of the common good. Paul himself states it when he says: “Even as I also am of Christ” (1 Cor 11:1). For nothing can so make a man an imitator of Christ as caring for his neighbours. Indeed, even though you fast, or sleep on hard ground, or even suffer onto death, but should you take no thought for your neighbour, you have done nothing great; despite what you have done, you still stand far from this model of a perfect Christian.
