Thus did paganism, chased out of the window of early Judaic Christianity, re-enter by all the doors, supplying the growing Church with the forms of psychic and literary attraction which ultimately served to give it a general hold over the ignorant and uncivilized masses of decadent and barbaric Europe. [441] Even with that machinery, the Church was dissolving in universal schism when Constantine saved it--or at least its body--by establishing it. As the Church broadened its basis, especially after its establishment, its assimilation of pagan ideas, names and practices, became so general that the process has long been made a standing ground of Protestant impeachment of the Church of Rome. [442] Middleton's Letter from Rome (1729) may be said to begin the scientific investigation, which is still going on. [443] Of that process the myth-theory is simply the attempted scientific consummation. It is resisted as every previous step was resisted, before and after Middleton, partly in sincere religious conviction, partly on the simple instinctive resentment felt for every "upsetting" theory about matters which men have habitually taken for granted. Some of the best reasoned resistance comes from professional theologians who have been disciplined by the habit of exact argument in the documentary field; some of the worst, as we have seen, comes from professed rationalists or Neo-Unitarians, who bring to the problem first and last the temper of spleen and bluster which history associates with the typical priest. Bluster never settles anything: argument, given free play under conditions which foster the intellectual life, in the end settles everything, even for the emotionalists who worship their instincts. But as historical like physical science is a process of continuous expansion and reconsideration, there can in this contest be no "triumph" for anything but the principle of unending renewal of thought, which is but an aspect of the principle of life. Insofar as the solution now offered is inadequate, it will in due course be improved upon; insofar as it is false, it will be ousted.
