The Ante-Nicene Christian library is meant to comprise translations into English of all the extant works of the Fathers down to the date of the first General Council held at Nice in A.D. 325. The sole provisional exception is that of the more bulky writings of Origen. It is intended at present only to embrace in the scheme the Contra Celsum and the De Principiis of that voluminous author; but the whole of his works will be included should the undertaking prove successful.
