You mean the Ignatian forgeries (15 letters)? Many scholars, including Philip Schaff have made some very valid points in regards those so called (15) 'Ignatian letters':
From: Philip Schaff: Ante-Nicene Fathers, Vol. I, Introductory Note To The Epistle Of Ignatius To The Ephesians.
The epistles ascribed to Ignatius have given rise to more controversy than any other documents connected with the primitive Church. As is evident to every reader on the very first glance at these writings, they contain numerous statements which bear on points of ecclesiastical order that have long divided the Christian world; and a strong temptation has thus been felt to allow some amount of prepossession to enter into the discussion of their authenticity or spuriousness. At the same time, this question has furnished a noble field for the display of learning and acuteness, and has, in the various forms under which it has been debated, given rise to not a few works of the very highest ability and scholarship. We shall present such an outline of the controversy as may enable the reader to understand its position at the present day.
There are, in all,
fifteen Epistles which bear the name of Ignatius. These are the following: One to the Virgin Mary, two to the Apostle John, one to Mary of Cassobelae, one to the Tarsians, one to the Antiochians, one to Hero, a deacon of Antioch, one to the Philippians; one to the Ephesians, one to the Magnesians, one to the Trallians, one to the Romans, one to the Philadelphians, one to the Smyrnaeans, and one to Polycarp. The first three exist only in Latin: all the rest are extant also in Greek.
It is now the universal opinion of critics, that the first eight of these professedly Ignatian letters are spurious. They bear in themselves indubitable proofs of being the production of a later age than that in which Ignatius lived. Neither Eusebius nor Jerome makes the least reference to them; and they are now by common consent set aside as forgeries, which were at various dates, and to serve special purposes, put forth under the name of the celebrated Bishop of Antioch.
But after the question has been thus simplified, it still remains sufficiently complex.
Of the seven Epistles which are acknowledged by Eusebius (Hist. Eccl., iii. 36), we possess two Greek recensions, a shorter and a longer. It is plain that one or other of these exhibits a corrupt text, and scholars have for the most part agreed to accept the shorter form as representing the genuine letters of Ignatius. This was the opinion generally acquiesced in, from the time when critical editions of these Epistles began to be issued, down to our own day. Criticism, indeed, fluctuated a good deal as to which Epistles should be accepted and which rejected. Archp. Usher (1644), Isaac Vossius (1646), J. B. Cotelerius (1672), Dr. T. Smith (I709), and others, edited the writings ascribed to Ignatius in forms differing very considerably as to the order in which they were arranged, and the degree of authority assigned them, until at length, from about the beginning of the eighteenth century, the seven Greek Epistles, of which a translation is here given, came to be generally accepted in their shorter form as the genuine writings of Ignatius.
Before this date, however,
there had not been wanting some who refused to acknowledge the authenticity of these Epistles in either of the recensions in which they were then known to exist. By far the most learned and elaborate work maintaining this position was that of Daillé (or Dallaeus), published in 1666. This drew forth in reply the celebrated Vindiciae of Bishop Pearson, which appeared in 1672. It was generally supposed that this latter work had established on an immoveable foundation the genuineness of the shorter form of the Ignatian Epistles; and, as we have stated above, this was the conclusion almost universally accepted down to our own day. The only considerable exception to this concurrence was presented by Whiston, who laboured to maintain in his Primitive Christianity Revived (1711) the superior claims of the longer recension of the Epistles, apparently influenced in doing so by the support which he thought they furnished to the kind of Arianism which he had adopted.
But although the shorter form of the Ignatian letters had been generally accepted in preference to the longer,
there was still a pretty prevalent opinion among scholars, that even it could not be regarded as absolutely free from interpolations, or as of undoubted authenticity. Thus said Lardner, in his Credibility of the Gospel History (1743): "have carefully compared the two editions, and am very well satisfied, upon that comparison, that the larger are an interpolation of the smaller, and not the smaller an epitome or abridgment of the larger.... But whether the smaller themselves are the genuine writings of Ignatius, Bishop of Antioch, is a question that has been much disputed, and has employed the pens of the ablest critics. And whatever positiveness some may have shown on either side, I must own I have found it a very difficult question."
This expression of uncertainty was repeated in substance by Jortin (1751), Mosheim (1755), Griesbach (1768), Rosenmüller (1795), Neander (1826), and many others; some going so far as to deny that we have any authentic remains of Ignatius at all, while others, though admitting the seven shorter letters as being probably his,
yet strongly suspected that they were not free from interpolation. Upon the whole, however, the shorter recension was, until recently, accepted without much opposition, and chiefly in dependence on the work of Bishop Pearson above mentioned, as exhibiting the genuine form of the Epistles of Ignatius.
But a totally different aspect was given to the question by
the discovery of a Syriac version of three of these Epistles among the mss. procured from the monastery of St. Mary Deipara, in the desert of Nitria, in Egypt. ...
... "
Exactly three centuries and a half intervened between the time when three Epistles in Latin, attributed to St. Ignatius, first issued from the press, and the publication in 1845 of three letters in Syriac bearing the name of the same apostolic writer. Very few years passed before the former were almost universally regarded as false and spurious; and it seems not improbable that scarcely a longer period will elapse before the latter be almost as generally acknowledged and received as the only true and genuine letters of the venerable Bishop of Antioch that have either come down to our times, or were ever known in the earliest ages of the Christian Church."
Had the somewhat sanguine hope thus expressed been realized, it would have been unnecessary for us to present to the English reader more than a translation of these three Syriac Epistles. But
the Ignatian controversy is not yet settled. There are still those who hold that the balance of argument is in favour of the shorter Greek, as against these Syriac Epistles. They regard the latter as an epitome of the former, and think the harshness which, according to them, exists in the sequence of thoughts and sentences, clearly shows that this is the case. We have therefore given all the forms of the Ignatian letters which have the least claim on our attention.
The reader may judge, by comparison for himself, which of these is to be accepted as genuine, supposing him disposed to admit the claims of any one of them. We content ourselves with laying the materials for judgment before him, and with referring to the above-named works in which we find the whole subject discussed.
As to the personal history of Ignatius, almost nothing is known. ..." -
