Here is what Wikipedia says....The Ante-Nicene Fathers, subtitled The Writings of the Fathers Down to A.D. 325, is a collection of books in 10 volumes (one volume is indexes) containing English translations of the majority of Early Christian writings. The period covers the beginning of Christianity until before the promulgation of the Nicene Creed at the First Council of Nicaea. The translations are very faithful, and provide valuable insights into the spirituality and theology of the early Church fathers.The series was originally published between 1867 and 1873 by the Presbyterian publishing house T. & T. Clark in Edinburgh under the title Ante-Nicene Christian Library (ANCL), as a response to the Oxford movement's Library of the Fathers which was perceived as too Roman Catholic. The volumes were edited by Rev. Alexander Roberts and James Donaldson. This series was available by subscription, but the editors were unable to interest enough subscribers to commission a translation of the homilies of Origen.In 1885 the Christian Literature Company, first of Buffalo, then New York, began to issue the volumes in a reorganized form, edited by the Episcopalian bishop of New York, A. Cleveland Coxe. Coxe gave his series the title The Ante-Nicene Fathers. By 1896, this American edition/revision was complete. In 1897, a volume 9, which contained new translations, was published by T. & T. Clark as an additional volume, to complete the original ANCL. Apart from volume 9, the contents entirely derived from the ANCL, but in a more chronological order. Coxe added his own introductions and notes, which were criticized by academic authorities and Roman Catholic reviewers.T. & T. Clark then associated with the Christian Literature Company and with other American publisher for the publication of the Nicene and Post-Nicene Fathers. I know of the collect, though only having read bits and pieces, and by no means familiar with it. I have viewed A. J. Tomlinson's set of these books over at the COGOP archives. It is said that he focused on the writing of the Apostolic Fathers (which he quoted sometimes in his writings), who were the church leaders who directly followed and knew the Apostles and their ministry. Your reference strikes me as much closer to the time of the counsel and creed, and the institutionalization of the church that separates the priest from the laity. In other words it sounds to Catholic for my restorationalist (if that's a word) ears.
