The African Christian Democratic Party (ACDP) on Sunday slammed church leaders for giving suspended ANC Youth League President Julius Malema a platform from which to attack political leaders at an Easter service on Friday.
Malema told a congregation in Butterworth in the Eastern Cape that he would not be silenced and asked churches to pray for him.
This was just two days after the ANC ruled that he may not carry out any official duties as a member of the party and may not address crowds in his capacity as league leader.
The ACDP's Kenneth Meshoe said Malema's address at the church could lead to divisions.
"It was very irresponsible for those church leaders to open the church for Malema to come in and bring in a political message," he said.
ANC secretary general Gwede Mantashe said Malema did not violate conditions of his suspension by addressing the church.
Malema was suspended last week after he accused President Jacob Zuma of running a dictatorship.
Malema has threatened to take the party to court if it does not lift his suspension.
Meanwhile, the ANC Youth League was expected to hold a crisis meeting on Monday.
