truth or falsity? It must be either divine revelation distinctly and certainly made known, or pure human reason. Every one who thinks logically must select between the two. As we have before said, we judge it by the criterion of revelation. What is the Christian, that is, what is the Catholic doctrine, founded on the veracity of God, clearly declared, and unalterable? We have already stated it, and it is known to all men. Those who still profess that they have in the Scriptures interpreted by their own private judgment an infallible rule of faith, are bound to demonstrate that their doctrine is clearly taught in the Scriptures, or is at least compatible with what is taught in them. It is open to any Catholic writer to discuss the matter with them on that ground if he thinks fit to do so, and it may be of some utility. It is equally suitable to discuss the question on purely philosophical grounds with those who do not admit revelation. But, as this is not our present purpose, we confine ourselves to the statement of what is the Catholic doctrine, and merely affirm that it is impossible to bring any conclusive argument against it, either from Scripture or from reason. It is really only the objections from reason which have any weight in the minds of men. Now, it is impossible to prove from reason that God may not propose to intelligent creatures a supernatural end to be attained by their voluntary operation under a moral law, and fix definite limits to their probation; or that it is not just to leave those who have misused their liberty by turning away from their prefixed end, in the permanent state of privation of their sovereign good. Nor is it possible to prove that penalties are not justly inflicted as a retribution for violations of law, in the state which succeeds the term of probation. It is God alone who is the judge of the nature and quantity of retribution which is due according to justice to individual demerits. Reason is not qualified to criticise the divine judgment which has decreed an eternal penalty for sin. The only rational mode of inquiring into the penalty for sin in the future life, is by seeking to ascertain what the divine revelation actually discloses and teaches on this momentous subject. This is determined with certainty by the Catholic rule, and taking all that is contained in this certain doctrine as a point of departure and a regulating principle, a theological and philosophical exposition of its relations with the other known principles and doctrines of revelation and reason manifests its harmony with all these truths, in a sufficiently clear light to command a firm rational assent. If all difficulties and obscurities are not completely removed, many misconceptions and apparent objections are dissipated, while the obscurity which finally remains is shown to be a necessary accompaniment of the dim light, by which the human mind, in its present condition,
