15. Some, it is true, [actually] preach Christ (the Messiah) [for no better reason than] out of envy and rivalry (party spirit), but others are doing so out of a loyal spirit and goodwill.
16. The latter [proclaim Christ] out of love, because they recognize and know that I am [providentially] put here for the defense of the good news (the Gospel).
17. But the former preach Christ out of a party spirit, insincerely [out of no pure motive, but thinking to annoy me], supposing they are making my bondage more bitter and my chains more galling.
18. But what does it matter, so long as either way, whether in pretense [for personal ends] or in all honesty [for the furtherance of the Truth], Christ is being proclaimed? And in that I [now] rejoice, yes, and I shall rejoice [hereafter] also.
