Protestant (Luther, 1483-1546)
This label denotes those Christians who trace their origin to
the Reformation precipitated by Martin Luther in a move to
reform the Catholic Church in the 16th century. Their aim
as to restore the Christian faith as it had been at its beginning.
In a word they "protested" the abuses in faith and practice
found in the Church during the Middle Ages.
Reformed (Zwingli, 1484-1531; Calvin, 1509-1564)
This label is used for those Protestant Christian believers
who follow the doctrines and polity of the Protestant
Reformers Zwingli and Calvin rather than the Lutheran
tradition. A chief distinction is in the belief in the Eucharist:
their faith holds a memorial view of the sacrament.
