I located the quote, and yes, there seems to be more to it that our apologists were summarizing:
In the thirteenth year of the sixth indiction364 some bishops from Asia came to Constantinople on business and stayed with us. Besides these, there were other bishops, including one from Scythia, Theotimus,365 one from Thrace, Ammon the Egyptian, and one from Galatia, Arabianus----all metropolitans, advanced in years; making a total of twenty-two bishops.366 A certain Eusebius, from the district known |118 as Kilbia, Bishop of Valentinopolis,367 took the opportunity of these being assembled and holding communion together to come forward in the assembled synod,368 on the first day of the week, and lay memorials before it, against Antoninus, Bishop of Ephesus; to these charges, so as to be in order, he of course prefixed the name of John. The charges fell under seven heads; first, that he had melted down Church plate, and placed the proceeds to the account of his son; second, that he had carried away marble from the entrance of the baptistery, and used it for the improvement of his own bathroom; next, that he had set up pillars belonging to the Church, which had been in position for many years, in his own dining-room; fourth, that his servant had committed murder, and that he was still keeping him in his service, without bringing him to trial; fifth, that he had sold some land bequeathed to the Church by Basilina, the mother of King Julian, and kept the money; sixth, that after separating from 369 his married wife, he had taken her again, and had had children born to him by her; seventh, that he regarded it as law, and dogma, to sell consecration to bishopricks at prices in proportion to the emoluments. He added that there were persons present who had paid such money, and been consecrated, as well as the man who had received it; and that he had proofs of his statements. |119
369. 3 The word is frequent for "saying good-bye to" (Luke ix. 61, etc.), so for "renouncing the world," "retiring to the desert as a monk," etc. According to the "Apostolic Canons," only the lower orders of clergy were allowed to marry after their appointment to office; the Council in Trullo ordered that a bishop's wife should retire to a convent, or become a deaconess; that of Caesarea, that if a priest marries after ordination he must be degraded. For Antoninus to resume relations with his wife was equivalent to marriage after ordination. It was proposed at the Council of Nicaea that married clergy should be compelled to separate from their wives, but the proposal was rejected; though it was generally held that the relations of bishops with their wives should be those of brother and sister. Cf. pp. 129, 136.http://www.tertullian.org/fathers/palladius_dialogus_02_text.htm#C14
In other words, he had take monastic vows, and then broke them, in addition to enriching his children's inheritence at the Church's expense.
I can't help but wonder if the omission that Antonius was a bishop, not just a priest, is intentional. Latin apologists are always quick to point out that we don't have married bishops (but then, we don't have one "living in perfect continence" either).
