Thus said Lardner, in his Credibility of the Gospel History

[Mary Naeem]

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.”
