Hi Sopho – I‘ve put these quotations into Google and found that they are used by certain hell booster (as opposed to hell buster) sites as evidence
However, note that this Clement – the Clement of the Clementine - is not Clement of Alexandria the Universalist.
The Clementines, which are made up of the “Recognitions of Clement” and “The Clementine Homilies”, are a religious romance purported to be composed by Pope Clement I. The story represents his search and induction into the Christian faith by Peter. The Latin form is the “Recognitions of Clement” consists of ten books. It is a translation made from the Greek by Rufinus, who died in 410. (The Greek, from which it was translated, is no longer in existence). The Greek form is “The Clementine Homilies” consists of twenty books
**It was long believed that the early date of the Clementines was proved by the fact that they were twice quoted by Origen. **One of these quotations occurs in the Philokalia of Sts. Gregory of Nazianzus and Basil (c. 360). Dr. Armitage Robinson showed in his edition of that work (1893) that the citation is an addition to the passage of Origen made by the compilers, or possibly by a later editor. The other citation occurs in the old Latin translation of Origen on Matthew. This translation is full of interpolations and alterations, and the passage of Pseudo-Clement is apparently an interpolation by the translator from the Arian Opus imperfectum in Matt.
Omitting Origen, the earliest witness is Eusebius. In his Ecclesiastical History, III, xxxviii (AD 325) he mentions some short writings and adds:
“And now some have only the other day brought forward other wordy and lengthy compositions as being Clement’s, containing dialogues of Peter and Appion, of which there is absolutely no mention in the ancients.”
This sounds like an ancient attempt to smear universalists by implying that Origen approved of a source that affirms ECT against him. I’ve scanned one article suggesting that the Clementines was the work of the Christian Cathetical school of Antioch since they show disapproval of the school of Alexandria (to which Origen belonged). Another article has suggested that the Clementines were produced but the Ebionites – Judaising Christians who demanded circumcision and scrupulous Torah observance of converts.
I’ve not found a wonderful article on them – so keep looking – but from the bits and bobs I’ve seen (wikipedia stub and google books on Ante Nicene Fathers) what I have written and pasted above seems to be true.
