Tertullian: Part I: Chapter VI.

Chapter VI.

To the testimony of antiquity is added that of later games instituted in their turn, and betraying their origin from the titles which they bear even at the present day, in which it is imprinted as on their very face, for what idol and for what religious object games, whether of the one kind or the other, were designed. You have festivals bearing the name of the great Mother 355 and Apollo of Ceres too, and Neptune, and Jupiter Latiaris, and Flora, all celebrated for a common end; the others have their religious origin in the birthdays and solemnities of kings, in public successes in municipal holidays.  There are also testamentary exhibitions, in which funeral honours are rendered to the memories of private persons; and this according to an institution of ancient times. For from the first the “Ludi” were regarded as of two sons, sacred and funereal, that is in honour of the heathen deities and of the dead. But in the matter of idolatry, it makes no difference with us under what name or title it is practised, while it has to do with the wicked spirits whom we abjure.  If it is lawful to offer homage to the dead, it will be just as lawful to offer it to their gods: you have the same origin in both cases; there is the same idolatry; there is on our part the same solemn renunciation of all idolatry.
