He [Jesus] therefore acknowledges that whatever God has enjoined ought to be performed, and that no part of it ought to be omitted, but maintains that zeal for the whole Law is no reason why we ought not to insist chiefly on the principal points. Hence he infers that they overturn the natural order who employ themselves in the smallest matters, when they ought rather to have begun with the principal points; for tithes were only a kind of appendage. Christ therefore affirms that he has no intention to lessen the authority even of the smallest commandments . . . . It is therefore our duty to preserve entire the whole Law . . . Hence we conclude that all the commandments are so interwoven with each other, that we have no right to detach one of them from the rest.While on the one hand tithes are called an “appendage,” he also referred to preserving the entire law, even the smallest commandment. Thus, Calvin appears to say that tithing continues into the New Covenant. Powers concludes: “[T]he fact that Calvin placed major emphasis upon ‘the principal points of the law’ did not lessen his belief in the tithe as the stipulated method of giving.”
