Any theologian who wrote oposing obout st Augustine's idea of sin?

One theologian who wrote opposing views about St. Augustine's idea of sin is Pelagius. Pelagius rejected the concept of original sin and believed that individuals have the ability to choose good or evil without the need for divine grace. He argued that humans are born morally neutral and can achieve salvation through their own efforts and free will. This view directly contradicted Augustine's belief in the inherent sinfulness of humanity and the necessity of divine grace for salvation. The debate between Augustine and Pelagius over the nature of sin and grace was a significant theological controversy in the early Christian church.
