Moulton and Milligan express their view of ONOMA (Philippians 2) when writing:
"By a usage similar to that of the Heb. SHEM, ONOMA comes in the NT to denote the character, fame, authority of the person indicated (cf. Phil. 2:9f, Heb 1:4). With this may be compared the use of the word as a title of dignity or rank, as in P Oxy I.58.6 (A.D. 288) where complaint is made of the number of officials who have devised 'offices' for themselves--ONOMATA hEAUTOIS EXEURONTES, and provision is made that, on the appointment of a single trustworthy superintendent, the remaining 'offices' shall cease-14f. TA DE LOIPA ONOMATA PAUSHTAI."
