When Timothy comes, see that you put him at ease among you, for he is doing the work of the Lord, as I am.  So let no one despise him. Help him on his way in peace, that he may return to me, for I am expecting him with the brothers. 1 Cor. 16:10-11 (ESV)
Timothy was a young man, a student of the gospel under Paul, and one of the first pastors of the church. Paul instructs the Church at Corinth to put him at ease among them. That is to take care of him, and listen to him, for he is doing the work of the Lord. It often happens that young pastors, are despised by their congregations, or people in the congregation, though they teach what is right and proper, and preach the gospel. If the pastor is preaching false doctrine than something needs to be done. But one ought to be very careful that the pastor is teaching falsely before making accusations. It may be that one’s own position needs to be examined and corrected. Pastors give up a lot to go to seminary and study God’s word, most are very sincere in their beliefs. That doesn’t mean that they aren’t sincerely wrong. But they should even then be treated with respect, as Priscilla did for Apollos, and waited till they were in private to instruct him, so as not to embarrass him in public. This may have made Apollos much more willing to accept her correction, and instruction. Her work certainly bore much fruit through the later work of Apollos.
