Jamieson, Fausset and Brown on Philippians 1:18

18. What follows from this? Does this trouble me as they thought it would? "Notwithstanding" their unkind thought to me, and self-seeking intention, the cause I have at heart is furthered "every way" of preaching, "whether in pretense (with a by motive, Php 1:16) or in truth (out of true 'love' to Christ, Php 1:17), Christ is proclaimed; and therein I do rejoice, yea, and I will rejoice." From this it would seem that these self-seeking teachers in the main "proclaimed Christ," not "another Gospel," such as the Judaizers in Galatia taught (Ga 1:6-8); though probably having some of the Jewish leaven (see on Php 1:15,16), their chief error was their self-seeking envious motive, not so much error of doctrine; had there been vital error, Paul would not have rejoiced. The proclamation of Christ," however done, roused attention, and so was sure to be of service. Paul could thus rejoice at the good result of their bad intentions (Psa 76:10; Is 10:5, 7).
