After these statements, Celsus, from a secret desire to cast discredit upon the Mosaic account of the creation, which teaches that the world is not y… - Origen

For God the Creator makes some vessels "unto honor" and he makes other vessels "unto dishonor"; but it is that vessel which has purged itself from all impurity that he makes a "vessel unto honor," while the one which has stained itself with low vices he makes a "vessel unto dishonor," And so we conclude from this that the cause of each man's activities goes back into the past and that each was made by God a vessel of honor or of dishonor in accordance with his merits.

In this way, then, by the renewal of the ceaseless working of Father, Son, and Holy Spirit in us, in its various stages of progress, shall we be able at some future time perhaps, although with difficulty, to behold the holy and the blessed life, in which (as it is only after many struggles that we are able to reach it) we ought so to continue, that no satiety of that blessedness should ever seize us; but the more we perceive its blessedness, the more should be increased and intensified within us the longing for the same, while we ever more eagerly and freely receive and hold fast the Father, and the Son, and the Holy Spirit. But if satiety should ever take hold of any one of those who stand on the highest and perfect summit of attainment, I do not think that such an one would suddenly be deposed from his position and fall away, but that he must decline gradually and little by little, so that it may sometimes happen that if a brief lapsus take place, and the individual quickly repent and return to himself, he may not utterly fall away, but may retrace his steps, and return to his former place, and again make good that which had been lost by his negligence.

And he asserts that certain persons who do not wish either to give or receive a reason for their belief, keep repeating, "Do not examine, but believe!" and, "Your faith will save you!" And he alleges that such also say, "The wisdom of this life is bad, but that foolishness is a good thing!" To which we have to answer, that if it were possible for all to leave the business of life, and devote themselves to philosophy, no other method ought to be adopted by any one, but this alone. For in the Christian system also it will be found that there is, not to speak at all arrogantly, at least as much of investigation into articles of belief, and of explanation of dark sayings, occurring in the prophetical writings, and of the parables in the Gospels, and of countless other things, which either were narrated or enacted with a symbolic signification, (as is the case with other systems). But since the course alluded to is impossible, partly on account of the necessities of life, partly on account of the weakness of men, as only a very few individuals devote themselves earnestly to study, what better method could be devised with a view of assisting the multitude, than that which was delivered by Jesus to the heathen?
