Filipenses 1:15

Of these local Roman Christians who were now witnessing and preaching more boldly there were two types, distinguished by their motivation. Some were hoping to advance their own reputations by their activities. They were envious of Paul’s prominence and were striving with their fellow believers for selfish reasons. This view seems more probable than that they were the Judaizers Paul spoke of later in Philippians 3:1-16. Others had a sincere desire to reach the lost and to meet the needs that Paul’s confinement had created.
