When Peter's successors planted a Judaic sect on the ruins of this paganism they had only to follow the genius of Numa's religion in the creation of the Catholic Church--the _civitas Dei_. Here, we may feel, an essential element of the new religion--the idea of the Kingdom of God--came naturally to supplant the older State religion; and the conception of the nation as a family was eminently germane to the fraternal maxims which grouped round the idea of the _ecclesia_. But old Rome as it had not stopped to inquire concerning small things, so it had never penetrated to interior things, and the Kingdom of God translated into the language of Rome lost in the process all its interior characters. What was delicate and subtle had never entered into Roman religion, but neither had what was petty, extravagant, or indecorous. Religion was no delicate aroma, but a concrete duty; not an individual choice, nor an individual necessity, nor an individual attraction, but a public rite, a public piety, a public decorum: and these characteristics, as we shall see, inhere in Roman religion to-day. It is in its liturgy that the mind, or if one may call it so, the temperament of the Roman Church found an ample and worthy expression; and it is in what it lacked as much as in what it put forward that the genius of the Roman rite is seen to differ entirely from that which presided at the making of the mass in every other part of Christendom. The effusion the imagery and the gracious parts added from Gaul, the mysticism of the Oriental, the philosophy of Greece, the Northern inwardness and intimacy, contributed nothing to it. Like Roman religion itself it was not a creation of the imagination or the intellect, nor the outcome of devotional sentiment; it was the creation of the Christian polity clothing its religious data, its religious certitudes, in a becoming garment--giving them a form, expression, a public characterisation. If there was no effusion there was largeness; in place of tenderness there was disengaged from the formal stately public act a perfect liberty of spirit. All through it was the public act itself which justified and consecrated, which was the sanction of the reality the criterion of the fitness of worship. Here besides, _sacramenta_ were not mere signs nor _symbola_ mere figures--they were stately vehicles of universal realities, always and everywhere adequate, worthy, co-ordinating, effectual. Roman ritual was quite bare of those things which in England and France are thought ritualistic; its only ritual consisted in the so-called "manual acts," that is, in the things which had to be done; those very things which the Eastern Church removed from the sight of the congregation, creating a "ritual" as a superfluous symbolism to engage the attention of the people. But the Roman dealt in real things, not imagery; nakedly setting forth his _sancta_ in the dry light of a realism which had no reticence joined to a great reticence of the emotions.
