In the second part of this series, Augustine switches his focus to a group that were also threatening the church of his day in that they believed that the church must be perfect and faultless in all it does. The Donatists, started to refuse to be baptised or taught by anyone that they felt was a traitor to the faith since they were the only true church that was allowed to administer sacraments and teach the ways of God to the world. Augustine quickly fought back against this group bringing all their arguments forward to be thought through and condemned by one of the greatest thinkers and theologians of the early church.
