The Lord commands us to do “good unto all men,” universally, a great part of whom, estimated according to their own merits, are very undeserving; but here the Scripture assists us with an excellent rule, when it inculcates, that we must not regard the intrinsic merit of men, but must consider the image of God in them, to which we owe all possible honour and love; but that this image is most carefully to be observed in them “who are of the household of faith,” inasmuch as it is renewed and restored by the spirit of Christ. Whoever, therefore, is presented to you that needs your kind offices, you have no reason to refuse him your assistance. Say he is a stranger; yet the Lord has impressed on him a character which ought to be familiar to you; for which reason he forbids you to despise your own flesh. Say that he is contemptible and worthless; but the Lord shows him to be one whom he has deigned to grace with his own image. Say that you are obliged to him for no services; but God has made him, as it were, his substitute, to whom you acknowledge yourself to be under obligations for numerous and important benefits. Say that he is unworthy of your making the smallest exertion on his account; but the image of God, by which he is recommended to you, deserves your surrender of yourself and all that you possess. If he not only deserved no favour, but, on the contrary, has provoked you with injuries and insults,–even this is no just reason why you should cease to embrace him with your affection, and to perform to him the offices of love. He has deserved, you will say, very different treatment from me. But what has the Lord deserved? who, when he commands you to forgive all men their offences against you, certainly intends that they should be charged to himself.
— John Calvin, quoted by Marilynne Robinson, “Open Thy Hand Wide: Moses and the Origins of American Liberalism,” in her collection When I Was a Child I Read Books.
According to Robinson, the much-derided Calvinist and Puritan strain in American Protestantism emphasized caring for the needy, because of, rather than in spite of, its supposed “legalism.” That is, because it valued the Old Testament more highly than some other Christian traditions, the Calvinist-Puritan synthesis was more influenced by the demands for social justice that are found in the Pentateuch. God’s “liberality” as expressed in these demands is at the root of “liberalism” as a project of institutionalizing justice for the poor.
