"Is that from the actual historical writings, or the forged ones???"
The Greek ones. Are they exactly what +Ignatius wrote? I haven't a clue. The Fathers certainly thought so. So far as I know, only heretics and pagans deny +Ignatius' Eucharistic theology. I do, however, try to stay away from anything spun in Latin or rewritten in much later Syriac versions.
Actually, iscoll has to rely totally upon the Church for every single word of scripture. He has no way of independently verifying that what Scripture is Scripture. But, that is never under consideration...I wonner why ?
