The Nicene Creed, produced at the First Council of Nicaea in 325 AD, was later amended (see Wikipedia) at the First Council of Constantinople in 381 AD and states :
( I am quoting excerpts from the original Greek and the literal English) :
Πιστεουμεν εις ενα θεον Πατερα [...]. . . . I believe in one God (the) Father [...]
και εις ενα Κυριον Ιησουν Χριστον . . . . . and in one Lord Jesus Christ,
τον υιον του θεου, τον μονογενη. . . . . . . the son of God, the only-begotten,
τον εκ του Πατρος γεννηθεντα . . . . . . . . that of the Father begotten
προ παντων των αιωνων [...] . . . . . . . . . . . before all the ages [...]
Francis Warden wrote a Ph.D. dissertation in 1938 which was summarised in 1953 in a journal and led to a publication by Dale Moody (also 1953) in the Journal of Biblical Literature which argued against the Nicene Creed's expression of 'only begotten' for the Greek word monogenes (used nine times in scripture) and argued that the meaning should be 'one of a kind' or 'unique'.
This is a strange thesis as that is what monos, by itself, means. Moody has failed to translate the -genes suffix and has ended up conveying the concept of solitude, rather than expressing the fact of a relationship, especially considering the nine contexts of intimate relationship recorded in scripture :-
Luke 7:12, 8:42, 9:38 Hebrews 11:17 John 1:14,18 3:16,18 I John 4:9.
Subsequently, Denny Burk, Professor of Biblical Studies at Boyce College (The Southern Baptist Theological Seminary, Kentucky) argued strongly against Dale Moody's conclusions. Also, Charles Lee Irons of the Fuller Theological Seminary argued against it and contributed to a book Retrieving Eternal Generation, Zondervan 2017, in which ten University Professors and three Assistant Professors argued unanimously in favour of the Nicene stance on the subject.
I am interested to know if there has been any response to the extensive research work of Burk, Irons and their compatriots and am interested to know if any further arguments, from the opposing faction, have been presented against this considerable resistance to Dale Moody's theory.
