In the aftermath of the persecutions, controversies arose over the sacraments, which required clarification of the Church's sacramental theology. Out of those controversies, new schisms emerged which had a correct understanding of the doctrine of the Trinity, but incorrect understandings of ecclesiology (the doctrine of the Church) and incorrect understandings of what makes a sacrament valid and effective. The significance of these schisms cannot be overstated, since it is still true to this day that the practice of rebaptism is one of the most prevalent acts of schism against the universal Church, and one of the greatest barriers to unity.
