“The word was used as a quasi philosophical term to express the doctrine quoted by St. Basil, in § 13:  it does not occur in the confession of Eunomius, which was prepared after this book, a.d. 382; but it was used by him in his Liber Apologeticus (before a.d. 365) against which St. Basil wrote.”  Rev. C.F.H. Johnston.  For “ὑπαρίθμησις” the only authorities given by the lexicons are “ecclesiastical.”  But the importation from the “wisdom of the world” implies use in heathen philosophy.
