Paul uses physis nine times consistently: never means 'custom'

Tom Schreiner notes Paul's uses: Jews 'by nature' (by birth), children of wrath 'by nature' (born in sin), natural branches (originally part of tree), Gentiles doing law 'by nature' (instinctively), uncircumcised 'by nature' (physically), not gods 'by nature.' Romans 1:26-27 and 1 Corinthians 11:14 indicate how people should act due to God's intended order. Paul NEVER once uses physis to mean custom.
