William of Rennes
William of Rennes, OP was a French friar in the Dominican Order, was a poet, theologian and expert on canon law. William was a Breton born in Thorigné in the thirteenth century. William wrote an "Apparatus ad summam Raymundi", a set of annotations to the Summa de casibus poenitentiae of Raymond of Peñafort. A summa is a summary of academic theology and canon law. In 1235 William argued that the baptism without the parental consent of Jewish children was suitable as Jews had a "servile status before Christians", he maintained that just as slaves have no parental rights due to their status, this fact also held true for the Jews, and as such the forced conversion of Jewish children was acceptable.
