Abstract
Coming from an astrological-magical tradition, the physician and radical reform theologian Paracelsus (1493/94–1541) developed 1530–1533 a new doctrine of the Eucharist based on the heavenly flesh of Christ and the need for spiritual rebirth. This teaching subsequently penetrated the thinking of many spiritualist theologians, mystics, and Paracelsists. At about the same time the spiritualist theologian Caspar Schwenckfeld (1489/90–1561) had developed a similar Eucharistic doctrine. This article discusses possible connections between the two men and presents building blocks for further research.
