Nope. There can't really be any apologetics here. All he did was make some statements. He makes some leaps, such as "they pray to pictures" (which in itself is not entirely true. We pray to those depicted. We venerate icons in order to venerate that which is depicted, not the depiction itself) becomes "bowing down, praying to idols." That's not the same thing as "pray to pictures." He also makes the statement, "The Bible says not to do that." He doesn't actually quote Scripture, much less expound on it in any way.
The only argument that kind of gives pause a little bit is his mentioning of the letter of St. Epiphanius of Salamis to St. Jerome, in which St. Epiphanius recounts entering a church and finding upon the curtain (apparently the altar curtain?) an image of Christ (or some saint). I found the passage. I'll give the full section for context. It's quite large. It reads:Moreover, I have heard that certain persons have this grievance against me: When I accompanied you to the holy place called Bethel, there to join you in celebrating the Collect, after the use of the Church, I came to a villa called Anablatha and, as I was passing, saw a lamp burning there. Asking what place it was, and learning it to be a church, I went in to pray, and found there a curtain hanging on the doors of the said church, dyed and embroidered. It bore an image either of Christ or of one of the saints; I do not rightly remember whose the image was. Seeing this, and being loth that an image of a man should be hung up in Christ's church contrary to the teaching of the Scriptures, I tore it asunder and advised the custodians of the place to use it as a winding sheet for some poor person. They, however, murmured, and said that if I made up my mind to tear it, it was only fair that I should give them another curtain in its place. As soon as I heard this, I promised that I would give one, and said that I would send it at once. Since then there has been some little delay, due to the fact that I have been seeking a curtain of the best quality to give to them instead of the former one, and thought it right to send to Cyprus for one. I have now sent the best that I could find, and I beg that you will order the presbyter of the place to take the curtain which I have sent from the hands of the Reader, and that you will afterwards give directions that curtains of the other sort— opposed as they are to our religion— shall not be hung up in any church of Christ. A man of your uprightness should be careful to remove an occasion of offense unworthy alike of the Church of Christ and of those Christians who are committed to your charge. Beware of Palladius of Galatia— a man once dear to me, but who now sorely needs God's pity— for he preaches and teaches the heresy of Origen; and see to it that he does not seduce any of those who are entrusted to your keeping into the perverse ways of his erroneous doctrine. I pray that you may fare well in the Lord.
-Letter 51 of Jerome, from Epiphanius to John of Jerusalem
It does need to be pointed out that St. Epihpanius is a pre-schism Orthodox saint, a contemporary of St. Jerome. He wrote many apologies against both the Arian and Origenian heresies. "Salamis" was a city of Cyprus. It's ruins
still stand today.
This does seem to be something to tackle. It seems, though, that it already has been. If you google "Epiphanius of Salamis iconclasm" for several pages of search results you will find nothing but links concerning the book Epiphanius of Salamis, Doctor of Iconoclam? Deconstruction of a Myth
by Fr. Stephen Bigham. The book was published by the Orthodox Research Institute in 2008 (according to Amazon
) and Fr. Stephen is an Orthodox priest, who has apparently done quite a bit of scholarship against the work of comtemporary iconoclasts (Protestants). In addition to this work, he has also penned Early Christian Attitudes towards Images
(also published by the Orthodox Research Institute).
I've flipped through a few reviews of these books by Fr. Stephen, and have yet to find a bad one. It seems that the book on St. Epiphanius gives texts that supposedly "prove" his iconoclasm, and does a good job airing both sides before concluding that these are fabrications, and that the holy saint never wrote such things, but that they were added by iconclasts (I suppose in the 8th or 9th century).
And that's about it. Hope that helped!
EDIT: I also feel that I should add how odd it sounds that if a saint (or even Christ) is depicted on the curtain, an Orthodox bishop would tear it down. I mean, God did command the Israelites to craft curtains with cherubim depicted on them..."Moreover thou shalt make the tabernacle with ten curtains of fine twined linen, and blue, and purple, and scarlet: with cherubim of cunning work shalt thou make them."
