I do not, however, concede to [Rome] that Paedobaptism had its origin in the Tradition of the Church. It certainly appears to be founded on the institution of God, and to have derived its origin from circumcision. It would have little foundation if it depended only on the will of man. Accordingly, we must hold it as an universal rule, that no Sacrament is legitimate, unless it be of God and not of men. But to return to the present subject; not only the Blessing of the Pascal taper, the Exorcism of Water, and similar follies, which are of endless number, but the ritual of the Mass, and all the impious worship of this description, they make perfectly pure by a simple process, by merely giving them the name of Traditions, so that everything to which time has given a kind of prescriptive right is, as it were, placed beyond controversy, and holds up its head among the commandments of God. Will no man oppose this? Nay, rather a thousand times incur the obloquy of disturbing the peace, than by perfidious dissimulation betray the essential truth which is here endangered.
