Crypto-Calvinism is a pejorative term describing a segment of those members of the Lutheran Church in Germany who were accused of secretly subscribing to Calvinist doctrine of the Eucharist in the decades immediately after the death of Martin Luther in 1546. It denotes what was seen as a hidden (crypto- from Greek: κρύπτω meaning "to hide, conceal, to be hid")[1] Calvinist belief, i.e., the doctrines of John Calvin, by members of the Lutheran Church. The term crypto-Calvinist in Lutheranism was preceded by terms Zwinglian and Sacramentarian. Also, Jansenism has been accused of crypto-Calvinism by Roman Catholics.[2]
