2. In 1:30 Paul writes, "And from/out-of him (God) you are in Christ Jesus
(EN CRISTWi IHSOU)." Since Paul seems to use KURIOS for Christ and QEOS or
PATHR for God (the Father), is it valid to interpret the next EN phrase (EN
KURIWi), which is in the hINA clause that follows in 1:31 (hINA...hO
KAUCWMENOS EN KURIWi KAUCASQW), to be a reference to Christ, rather than to
God the Father? I know the quote is derived from Jeremiah 9:24 where YHWH is
used. But could this be an instance like Philippians 2:9-11 where Paul takes
an OT scripture (Isaiah 45:23) and attributes to Christ what was said (by
Isaiah) about YHWH? (It's attributions to Christ of things that were in the
OT said about YHWH that seem to me to make an implicit case for the doctrine
of the Trinity that is just as strong as overt references (if there are any)
to Jesus being God.)
