It is very remarkable, that his pedigree should have been so accurately ascertained. The occasion was this: Porphyry, a great enemy to christianity, had represented the christians as being an ignorant people, destitute of science; but not being able to conceal the repute of Origen, for his uncommon skill in human literature, pretended that he had been at first a heathen, and had learned their philosophy. In order to confute this falsehood, Eusebius enquired into his ancestry, and set forth his christian descent. Origen was born in the year of our Lord 185, that is, eighty-five years after the apostles. He was seventeen years old when his father suffered martyrdom. He had himself, undoubtedly, been baptized in his infancy; and must have been informed concerning the practice of the apostles, respecting the baptizing of infants; for his grandfather, or at least his great-grandfather, lived in the apostolic times, and they both were christians. This is the man, who has expressly declared, that infants were baptized in his day, and that the church was directed by an order or tradition from the apostles, to baptize them. His circumstances were such as afforded him all the necessary and suitable means for obtaining information. We have no reason to suspect his credibility as a witness; and nothing can be more unreasonable, than to reject or treat his testimony with contempt. It is a circumstance worthy of our _very particular notice_, that Origen and the other ancient Fathers do not speak of infant-baptism as being a practice that was denied or opposed by any one. They mention it as a practice generally known and approved, and for the purpose of illustrating and confirming other points that were then disputed.
