More than 20 Anglican Church priests and a bishop joined hundreds of mourners at the funeral of Father Sandile Sithole in Daveyton, Ekurhuleni, on Friday.
Thirty-two-year-old Sithole is believed to have committed suicide because of "domestic problems".
His untimely death not only shocked his family and friends, but also his congregation.
A relative who did not want to be named told Sowetan that the cause of his death would only be known after the results of the postmortem were released.
"To say anything else would be pure speculation," he said.
In his tribute, Father Joe Mdhlela berated Sithole for his action.
"I cannot come to terms with the fact that at only 32, with a great future ahead of him, Sithole decided to die under unclear circumstances."
A source said Sithole was deeply hurt when his wife, Princess, left their home in Katlehong a week before her husband died on February 2.
It is believed she decided to leave following a domestic dispute.
The four-hour funeral service, held at Christ the Redeemer Anglican Church in Daveytoni, was conducted by the Right Reverend David Beetge.
He was assisted by Reverend Gill Rookyard, Reverend Luke Pato, who delivered a homily, Father Livingston Ngewu, principal of the College of Transfiguration in Grahamstown, and Father Steven Mbande, who was Sithole's mentor and former rector.
Sithole is survived by his wife and two children.
