Did any of the founders of Protestantism (Luther, Calvin, Knox etc.) ever deny the Real Presence of Jesus in the Eucharist?
Luther affirmed the real presence.
Calvin and Knox and Bucer favored a spiritual presence.
Zwingli, and Bullinger favored a symbolic memorial.
Thank you for the prompt reply!
Bit more nuanced that this re: some of the ‘spiritual presence’ people. Lots of them wouldn’t set ‘spiritual’ up in opposition to ‘real’. Calvin seems to have a surprisingly intense concept of presence at some points; he just wants to avoid corporeality.
