_Dr. D._ TERTULLIAN was born at Carthage, not far from A.D. 150, that is, about fifty years after the apostles. He wrote, therefore, within a hundred years of the apostle John. But he was a man of peculiar views, extravagant in his opinions, an enthusiast in everything. He proves that the practice of infant baptism was established, by arguing against the expediency of baptizing children, and unmarried persons, lest they should sin after baptism. His argument, with respect to both these classes of persons, is the same. His language is, "If any understand the weight of baptismal obligations, they will be more fearful about taking them than of delay." He argued that baptism should be deferred till people were in a condition to resist temptation. These are his words: "Therefore, according to every person's condition, and disposition, and age, also, the delay of baptism is more profitable, especially as to little children. For why is it necessary that the sponsors should incur danger? For they may either fail of their promises by death, or may be disappointed by a child's proving to be of a wicked disposition. Our Lord says, indeed, 'Forbid them not to come to me.' Let them come, then, when they are grown up; let them come when they understand; let them come when they are taught whither they come; let them become Christians when they are able to know Christ. Why should their innocent age make haste to the forgiveness of sins? Men act more cautiously in temporal concerns. Worldly substance is not committed to those to whom divine things are entrusted. Let them know how to ask for salvation, that you may seem to give to him that asketh. "It is for a reason no less important that unmarried persons, both those who were never married, and those who have been deprived of their partners, should, on account of their exposure to temptation, be kept waiting," &c. As these extracts prove that the institution of marriage existed in Tertullian's day, so they prove the existence then of infant baptism. Nothing can be more conclusive. How pertinent and useful to his object would it have been, could he have assailed the practice of infant baptism as a human invention! He would not have failed to use that line of attack, had it been possible. Now, as certain articles in the newspapers, in a distant part of the country, remonstrating against the street-railroads, for example, prove that street-railroads exist there, so does Tertullian's argument against infant baptism prove that it was practised within one hundred years after the apostles. _Mr. M._ Is not this stronger, if anything, than Origen's testimony, being so much nearer the apostolic age? _Dr. D._ For that reason it may have more weight; but Origen's testimony, being direct and positive, is most easily quoted. He was near enough to the apostolic age for all the purposes of credible testimony. There is another historical testimony, if you wish to hear of more, which has great weight.
