One of the most controversial passages in the whole of the New Testament is what Paul has to say in Philippians 2:5-11, in which he talks of the Messiah, Yahushua, as existing of the "form" of God, but taking on the "form" of a slave, in the "likeness" of a human being.
The most interesting of the statements is that in Philippians 2:11, which is usually translated as "And every tongue will confess that Jesus Christ is Lord, to the glory of God the Father."
In the oldest manuscripts of the Renewed Covenant, there are what's known as the nomina sacra (see the introduction page to TWTY translation of the Renewed Covenant here), and a significant, shall we say, muddening of how one is to interpret the specific nomen sacrum ΚΣ (and its other forms of course), which can in contexts either refer to both Yahweh and Yahushua as "Master" or "Sovereign Master", or in many cases (especially anarthrous; that is, lacking a definite article the) is a direct reference to Yahweh, and not just a title.
One of these I would say is in Philippians 2:11, where unfortunately in P46 we don't have the entire verse extant, but in Codex Sinaiticus we do. The main phrase is ΚΣ ΙΣ ΧΣ, which rather than meaning "Yahushua Messiah [is] Sovereign Master", should be "Messiah Yahushua is Yahweh."
As the nomen sacrum ΚΣ has no definite article (ο = Greek "the"), there is no reason to think that this is being used as a placement for the title, but rather a direct reference to Yahweh.
