Zwingli on Greek

Zwingli: … He then, in order to show that Christ, although of Divine Nature, had taken upon Him the form of a servant, and been made like to us, cited in the Greek text the passage from Philip. ii.7.
Luther: Let the Greek alone, quote it in Latin or German.

Zwingli: Excuse me; during the last twelve years I have only made use of the Greek New Testament.
