In John Flavel’s Mystery of Providence he makes mention of a man named Pareus. Apparently Pareus had been apprenticed, by his mother, to be a pharmacist (apothecary). God, however, had contrary plans. Pareus ended up being a marevelous teacher during the Reformation period. He was irenic in nature and sought to bring reconciliation to the Lutherans and the Calvinists of his day. More information is given here:
