Independent Democrats president Patricia de Lille called on the ANC on Monday to stop using Biblical references in its election campaign after a regional party leader likened Jacob Zuma to Jesus.

"The ANC must be condemned in the strongest possible terms for its selective use of Christianity to further its political goals," De Lille said.

She accused the ANC of trying to portray itself and its leader as "god-like" and urged it to "stop using the Jesus Christ, the Bible and Christianity in general to garner votes from the poor and the vulnerable."

The fierce critic of the multi-billion rand arms deal said it was blasphemous to compare a politician facing corruption allegations with Jesus.

"We in the Independent Democrats would like to draw the ANC's attention to the fact that Jesus was never charged with corruption.

"Adultery, the machine gun song and Zuma's failure to condemn war talk and hate speech by the ANC rank and file are examples of why it is insulting to compare Zuma with Christ," she said.

The ID's call comes after the ruling party's Free State leader, Ace Magashule, said the ANC president was suffering just like Jesus Christ did, in an interview published on Monday.

"Jesus was persecuted. He was called names and betrayed. It's the same kind of suffering Mr Zuma has had to bear recently, but he's still standing strong. He's not giving up," Magashule said.

De Lille said it was one of several examples of religious rhetoric used by the ANC in the run-up to the national election.
