A.T. Robertson Commentary 1 Corinthians 4:17

"For this cause have I sent unto you Timothy, who is my beloved and faithful child in the Lord, who shall put you in remembrance of my ways which are in Christ, even as I teach everywhere in every church." — 1 Corinthians 4:17 (ASV)

Have I sent (επεμψα). First aorist active indicative. Probably Timothy had already gone as seems clear from 16:10f. Apparently Timothy came back to Ephesus and was sent on to Macedonia before the uproar in Ephesus (Acts 19:22). Probably also Titus was then despatched to Corinth, also before the uproar.

In every church (εν παση εκκλησια). Paul expects his teachings and practices to be followed in every church (1 Corinthians 14:33). Note his language here "my ways those in Christ Jesus." Timothy as Paul's spokesman

will remind (αναμνησε) the Corinthians of Paul's teachings. 1 Corinthians 4:18

Some are puffed up (εφυσιωθησαν). First aorist (effective) passive indicative of φυσιοω which see on verse 6.

As though I were not coming to you (ως μη ερχομενου μου προς υμας). Genitive absolute with particle (assuming it as so) with μη as negative.
