Phil 2:5-11

In my opinion it is highly unlikely that Phil. 2:5-11 is a pre-Pauline
hymn.  I could go on at some length.  Bibliography on the passage is
listed in W.G. Ku"mmel, Introduction to the New Testament, rev. ed.
London: SCM, 1975, pp. 334-35, n. 38.  The principal English work is
R.P. Martin, Carmen Christi, 1967.
