“‘Whosoever shall give you a cup of water to drink in my name, because ye belong to Christ, verily I say unto you, he shall not lose his reward.’ It has almost seemed that in every epoch there were some who were primarily interested in naming the name of Christ, clarifying its doctrinal and theological meaning, and defending that meaning against its enemies — but who named the name without giving the cup of water. Yet it has seemed possible for others to give the cup of water, to provide the healing, and to improve the social lot of the disadvantaged — but to do so without explicitly naming the name of Christ. Does that saying of Jesus mean that each of these ways of responding to his summons is only a partial obedience to this dual command?”
