If then there are normative principles of prayer, just as there are of action, thought and speech; if there are petitions which are not permissible, and which are not and never can be prayers, though by a spiritual fallacy, analogous to logical fallacies, they may be thought to be prayers, what is it that decides the nature of an admissible petition? It seems to be the conception of the being to whom the petition is addressed. Thus it is that prayer throws light on the idea of God. From the prayers offered we can infer the nature of the idea. The confusion of admissible and inadmissible petitions points to confused apprehension of the idea of God. It is not merely imperfect apprehension but confused apprehension. In polytheism the confusion betrays itself, because it leads to collision with the principles of morality: of the gods who make war upon one another, each must be supposed to hold himself in the right; therefore either some gods do not know what is right, or there is no right to be known even by the gods. From this confusion the only mode of escape, which is satisfactory both to religion and to morality, is to recognise that the unity of morality and the unity of the godhead mutually imply one another. But so long as a plurality of gods, with a shifting standard of morality, is believed in, the distinction between admissible and inadmissible petitions cannot be firmly or correctly drawn.
A tribal god is petitioned to slay the tribe's enemies, because he is conceived as the god of the tribe and not the god of its enemies. If the declaration, that 'I am thy servant,' is affirmed with emphasis on the first personal pronoun, so as to imply that others are no servants of thine, the implication is that thy servants' enemies are thy enemies; whereas if there is, for all men, one God only, then all men are his servants, and not one person, or one tribe, alone. The conception of God as the god of one tribe alone is an imperfect and confused apprehension of the idea of God. But it is less so than is the conception of a god as belonging to one individual owner, as a fetish does. To a fetish the distinctive, though not the only, prayer offered, precisely is 'Slay mine enemies'; and therein it is that lies the difference between a fetish and a god of the community. The difference is the same in kind as that between a tribal god and the God of all mankind. The fetish and the tribal god are both inadequate ideas of God; and the inadequacy implies confusion--the confusion of conceiving that the god is there only to subserve the desires and to do the will of the individual worshipper or body of worshippers.
