Mourners at the funeral of Ian Ogle have heard he died in a "courageous, fearless and selfless way".
Pastor Kevin Sambrook said there must be no revenge for his "brutal, barbaric and savage" murder.
Mr Ogle was stabbed and beaten in the street near his home at Cluan Place, east Belfast, on Sunday 27 January.
Meanwhile, a 40-year-old man and a 37-year-old man arrested by officers investigating the murder on Sunday and Monday respectively have been released.
Nine other people arrested in connection with the case last week - seven men and two women - have all since been released.
Mr Sambrook, who was with the father of two as he lay dying, told the congregation at the Covenant Love Church, Albertbridge Road, that the 45 year old had valued the lives of his son and daughter, who he was trying to protect, more than his own.
His daughter Toni Johnston paid tribute to him, saying "he was her mother's first and only love".
Mr Ogle was buried at Roselawn Cemetery.
