‘If God is male…’

Did John Piper make statements to redefine the nature of God (theology proper)? If God is male…’ « Shored Fragments:

Similarly, the 'God-as-masculine' thesis I am discussing here is strikingly revisionist and radical on the central topic of Christian theology, the doctrine of God.

Changing the former whilst claiming continuity on the latter is necessarily a thorough departure from the tradition.
