During the six centuries now under review the Roman Catholic Church and theology were the only Christianity publicly recognised. The heretics were few and powerless, and the papal system had full sway. Since the early part of the period specified, the working theology of the Roman Church has undergone but few, and, as pertaining to our subject, unimportant, changes or developments. Previous to that time her doctrinal scheme was inchoate, gradually assimilating foreign elements and developing itself step by step. The principal changes now concerning us to notice in the passage from patristic eschatology as deducible, for instance, from the works of Chrysostom, or as seen in the "Apostles' Creed" to mediaval eschatology as displayed in the "Summa" of Thomas Aquinas or in the Catechism of Trent are these. The supposititious details of the under world have been definitely arranged in greater subdivision; heaven has been opened for the regular admission of certain souls; the loose notions about purgatory have been completed and consolidated; and the whole combined scheme has been organized as a working instrument of ecclesiastical power and profit.
These changes seem to have been wrought out, first, by continual assimilations of Christianity to paganism,1 both in doctrine and ceremony, to win over the heathen; and, secondly, by modifications and growths to meet the exigencies of doctrinal consistency and practical efficiency, exigencies repeatedly arising from philosophical discussion and political opposition.
The degree in which papal Christianity was conformed to the prejudices and customs of the heathen believers, whose allegiance was sought, is astonishing. It extended to hundreds of particulars, from the most fundamental principles of theological speculation to the most trivial details of ritual service. We shall mention only a few instances of this kind immediately belonging to the subject we are treating. In the first place, the hierophant in the pagan Mysteries, and the initiatory rites, were the prototypes of the Roman Catholic bishop and the ceremonies under his direction.2 Christian baptism was made to be the same as the pagan initiation: both were supposed to cleanse from sin and to secure for their subject a better fate in the future life: they were both, therefore, sometimes delayed until just before death.3 The custom of initiating children into the Mysteries was also common, as infant baptism became.4 When the public treasury was low, the magistrates sometimes raised a fund by recourse to the initiating fees of the Mysteries, as the Christian popes afterwards collected money from the sale of pardons.
In the second place, the Roman Catholic canonization was the same as the pagan apotheosis. Among the Gentiles, the mass of mankind were supposed to descend to Hades at death; but a few favored ones were raised to the sky, deified, and a sort of worship paid to them. So the Roman Church taught that nearly all souls passed to the subterranean abodes, but that martyrs and saints were admitted to heaven and might lawfully be prayed to.5
Thirdly, the heathen under world was subdivided into several regions, wherein different persons were disposed according to their deserts. The worst criminals were in the everlasting penal fire of Tartarus; the best heroes and sages were in the calm meadows of Elysium; the hapless children were detained in the dusky borders outside the grim realm of torture; and there was a purgatorial place where those not too guilty were cleansed from their stains. In like manner, the Romanist theologians divided the under world into four parts: hell for the final abode of the stubbornly wicked; one limbo for the painless, contented tarrying of the good patriarchs who died before the advent of Christ had made salvation possible, and another limbo for the sad and pallid resting place of those children who died unbaptized; purgatory, in which expiation is offered in agony for sins committed on earth and unatoned for.6
