But if the idea of a Church is made to enter into the definition of religion, does that not exclude the private religions which the individual establishes for himself and celebrates by himself? There is scarcely a society where these are not found. Every Ojibway, as we shall see below, has his own personal _manitou_, which he chooses himself and to which he renders special religious services; the Melanesian of the Banks Islands has his _tamaniu_;[87] the Roman, his _genius_;[88] the Christian, his patron saint and guardian angel, etc. By definition all these cults seem to be independent of all idea of the group. Not only are these individual religions very frequent in history, but nowadays many are asking if they are not destined to be the pre-eminent form of the religious life, and if the day will not come when there will be no other cult than that which each man will freely perform within himself.[89]
But if we leave these speculations in regard to the future aside for the moment, and confine ourselves to religions such as they are at present or have been in the past, it becomes clearly evident that these individual cults are not distinct and autonomous religious systems, but merely aspects of the common religion of the whole Church, of which the individuals are members. The patron saint of the Christian is chosen from the official list of saints recognized by the Catholic Church; there are even canonical rules prescribing how each Catholic should perform this private cult. In the same way, the idea that each man necessarily has a protecting genius is found, under different forms, at the basis of a great number of American religions, as well as of the Roman religion (to cite only these two examples); for, as will be seen later, it is very closely connected with the idea of the soul, and this idea of the soul is not one of those which can be left entirely to individual choice. In a word, it is the Church of which he is a member which teaches the individual what these personal gods are, what their function is, how he should enter into relations with them and how he should honour them. When a methodical analysis is made of the doctrines of any Church whatsoever, sooner or later we come upon those concerning private cults. So these are not two religions of different types, and turned in opposite directions; both are made up of the same ideas and the same principles, here applied to circumstances which are of interest to the group as a whole, there to the life of the individual. This solidarity is even so close that among certain peoples,[90] the ceremonies by which the faithful first enter into communication with their protecting geniuses are mixed with rites whose public character is incontestable, namely the rites of initiation.[91]
