A caution against the influence of narrow prejudice is obviously more needful in relation to the persons and practices of ancient Christianity, than when common history is the subject of inquiry; for in whatever relates to religion, every one carries with him, not merely the ordinary prepossessions of time and country, but an unbending standard of conduct and temper, which he is forward to compare, in his particular manner, with whatever offends his notions of right. But though the rule of Scripture morals is unchangeable, and must be applied with uncompromising impartiality to human nature under every variety of circumstance, yet is it impractible, at the distance of upwards of a thousand years, so fully to calculate those circumstances, and so to perceive the motives of conduct, as is necessary for estimating fairly the innocence or the criminality of particular actions or habits of life. The question of abstract fitness, and that of personal blameworthiness, should ever be kept apart: at least they should be kept apart when it is asked—and we are often tempted to ask it in the perusal of church history—May such men be deemed Christians, who acted and wrote thus and thus? Before a doubt of this kind could be solved satisfactorily, we must know—what can never be known till the day of universal discovery—how much of imperfection and obliquity may consist with the genuineness of real piety; and again, how much of real obliquity there might be, under the actual circumstances of the case, in the conduct in question. Who can doubt that if the memorials of the present times, copious, and yet inadequate as they must be, shall remain to a distant age, they will offer similar perplexities to the future reader, who, amidst his frequent admiration or approval, will be compelled to exclaim—But how may we think these men to have been Christians? Christianity is in gradual process of reforming the principles and practices of mankind, and when the sanative operation shall have advanced some several stages beyond its present point, the notions and usages of our day, compared with the commands of Christ, as then understood, will, no doubt, seem incredibly defective.
