Lest any one think that we are dealing in mere argumentative subtleties, I shall turn to that highest authority of our “seal” itself. When entering the water, we make profession of the Christian faith in the words of its rule; we bear public testimony that we have renounced the devil, his pomp, and his angels. Well, is it not in connection with idolatry, above all, that you have the devil with his pomp and his angels? From which, to speak briefly— for I do not wish to dilate— you have every unclean and wicked spirit.
If, therefore, it shall be made plain that the entire apparatus of the shows is based upon idolatry, beyond all doubt that will carry with it the conclusion that our renunciatory testimony in the laver of baptism has reference to the shows, which, through their idolatry, have been given over to the devil, and his pomp, and his angels. We shall set forth, then, their several origins, in what nursing-places they have grown to manhood; next the titles of some of them, by what names they are called; then their apparatus, with what superstitions they are observed; (then their places, to what patrons they are dedicated;) then the arts which minister to them, to what authors they are traced.
If any of these shall be found to have had no connection with an idol-god, it will be held as free at once from the taint of idolatry, and as not coming within the range of our baptismal abjuration.
