Genesis 11:1
1The whole earth was of one language and of one speech.
One language and the same words is still a gift. Shared speech lets neighbors help one another; it is not yet the tower.
Classical Arminians start here with human capacity under common kindness. Unity of tongue is light they can use to fill the earth—or to huddle against God’s spreading word. The gift is no formality; what they do with it will soon be their own responsible choice.
Moses opens with a kindness: the whole earth still holds one speech. Calvin heard here God’s will that a sacred bond of society be retained by a common language.
Language is the Lord’s provision before it is a human tool. The later confusion will be adventitious punishment, not the original design. Providence already governs the world’s one lip.
