The armed men repeatedly pistol-whipped pastor Kobus Erasmus, before forcibly taking valuables away from members of the congregation.
The robbery was halted as Pieter van der Westhuizen, brother of late Springbok legend Joost, allegedly shot and killed two of the armed men.
The congregation has hailed Van der Westhuizen as a hero.
“Nobody told him to be the hero. He stood up at a moment when it was necessary. The people shot at him, they shot at us. A young boy was hurt as the shrapnel flew past him. The rest were shocked,” said Erasmus.
At time of publication, Van der Westhuizen's legal team said he has not been charged but is co-operating with police.
