Luther and Lewis

In addition to almsgiving or doing good to our neighbor, praying is another work that is appropriate to the Christian. Just as the necessities of this life requires us to do good to our neighbor and to sympathize with him in his need—after all, that is why we live together on earth, so that we might serve and help one another—so the constant threat to us in this life from every kind of inevitable danger and unavoidable need requires us to call upon God continually and to seek His help, both on our own behalf and on behalf of everyone else.—Martin Luther, AE 21:137

It must be most emphatically stated the the items or particulars included in a homogeneous class are almost the reverse of what St. Paul meant by members. By members he means what we should call organs, things essentially different from, and complementary to, one another: things different not only in structure and function but also in dignity.—C. S. Lewis, Business of Heaven, p. 210
