Only (monon). One item was emphasized. We should remember (mnhmoneuwmen). Present active subjunctive, "that we should keep on remembering." Which very thing (o--auto touto). Repetition of relative and demonstrative, tautology, "which this very thing." In fact Barnabas and Saul had done it before ( Acts 11:30 ). It was complete victory for Paul and Barnabas. Paul passes by the second public meeting and the letters to Antioch ( Acts 15:6-29 ) and passes on to Peter's conduct in Antioch.
