Julius Caesar
Octavius in Julius Caesar says the killing will stop when Caesar's death is avenged.
Octavius was Caesar's adoptive son but he was actually his nephew.
Octavian was Gaius Julius Caesar's nephew and was posthumously adopted by Caesar according to his will. At the time of the elder Caesar's assassination, Octavius was in military training in Apollonia, Illyria.
Antony is a devoted friend of Julius Caesar he is the one that speeks at the funeral after Brutus. Octavius is Julius Caesar's nephew and adopted son.
The only part of Act IV of Shakespeare's Julius Caesar that has Antony and Octavius in it is Scene 1, and the only other character on stage is Lepidus, who is a "tried and valiant soldier" and not a priest, nor does anyone yell at him. Perhaps you are thinking of a play called Julius Caesar by someone else.
