The Arrhabonarii were a Polish Christian sect who held that the Eucharist was not a present gift of grace but was a pledge of a gift to be bestowed in heaven.
[1] The sect's name is derived from the Greek Ἀρραβων, Arrha, meaning "earnest".
[2] The position was first argued by Francesco Stancaro in 1543.
